[@pausaniasofithaca6325]

Thanks very much for the detailed explanations. This feels like a fairly comprehensive introduction to me! I am a homeowner gearing up to DIY some electrical conduit in my new garage workshop, and I wanted to brush up on what I learned in high school physics with a new focus on working with electricity safely. I'm glad I found your channel; I think this video was just the ticket!

[@stillwill1808]

This is my favorite subscription by far. Ive relearned things I had forgotten and been set straight on things I thought I already knew for years. It will make you a much better troubleshooter.

[@ermiyastesfakiros9268]

Thanks so much. You are the best instructor I have seen in my age.

[@luis1250]

I’m a student, these explanations makes really easy to understand electricity, I know it is not exactly like that, but it’s enough to be introduced. Thanks

[@diomedesovalle2606]

You are a great teacher man! I usually have to watch videos about 3 times just to start understanding everything in the video. You teach me something new and then go further with explanations and stories and relating them to things i understand completely and it sticks. Love it man i didnt even start trade school yet but i feel like im ahead with these videos^

[@jameswagner2634]

Doesn’t matter how you get the point across or what illustrations you used to do that, the point is that people understand what you’re teaching them , don’t ever let anybody tell you anything different you don’t apologize for the way you teach ever. Just keep doing what you’re doing brother.😎🇺🇸🪖👍

[@corydg____]

Hey Brian, I really appreciate your videos. Your teaching style fits how I learn perfectly. I just found out you guys are in CFL and so am I. I’m currently a sales tech doing mostly IAQ and new unit sales, I only do light repair work rn. These videos have helped me a lot with those repairs. I would love to come help out for free on Sundays if you guys work those days. I just applied to the company as the kind lady on the phone told me that would be the best way to get in contact with you. I applied as an install helper. Would love to come help out on my day off with whatever you guys need.

[@Falcon-eh8tq]

I was listening to your podcast between calls and in one about gas and combustion you guys are discussing buildup/flaking of the inside of copper tubing? I live in Ontario and I See this sometimes in service and quite often in installation when removing old equipment (25+ sometimes the line is 35 years or older) and the line is still gas tight, mind you seriously work hardened. In service it's worse on LP but seems to happen on both NG and LP and it's not actually going to be an issue until someone hits the line & with no dirt pocket. i see it happen alot on fireplaces - might go into the gas valve, and people wonder why their fireplace flame is only a gentle blue rumble after rennovations in the living room 😅 Fireplaces that are 25 to 35 years or older, with a 3/8 gas line will shale bad enough around that age, ive seen it actually have enough of a static pressure drop to drop out the pilot when the burner is turned on. It would probably happen with larger size tubing too eventually, but i have yet to see it be a problem on 1/2" copper or bigger. and it can change flame appearance very slowly, over those years blowing out the line with compressed air once in the two decades can fix it. wrapping copper when passing thru and strapping against masonry has long been code here and no coastal salt todeal with, also galvanized is illegal - we see a ton of black iron, req. painted outdoors & CSST. I like copper because its cheap, effective and time tested. Only specified legal method of leak detection here is soap and dial, which make infractions based on electronic detection sketchy at best. Love the podcast man just want ed to leave my 2 cents.

[@Falcon-eh8tq]

Ill admit most folks dont maintain a fireplace long enough/often enough or use it often enough to have it get old enough for it to even be a topic of discussion lol. but we could knock out a cup full of flakes from 3 feet of tubing in some places! Its real man its not a conspiracy!

When you add additional resistive components to a circuit, the total resistance decreases. Just wanted to clear that up in case anyone was confused about that

You mean when they are added in parallel.

[@Monaco_mechanical]

Thank you so much. I love these videos

[@prestoncoleman718]

I hope this question makes sense: can someone please explain why there is less resistance when a motor is seized up? Wouldn’t it be more resistance impeding the path of the current trying to close circuit because it’s not turning freely making it harder or more resistant to turn? When he specified that we should understand resistance as the inverse of logical common sense way of thinking (like friction), I missed the explanation explaining why we should understand it that way.

[@EarlHayward]

The resistance is the same when a motor starts up that is seized or not seized. That is called locked rotor amps as there is massive current flow in both the rotor and the stator for a short period of time until the rotor gets up to normal speed. Then, there is back EMF that effectively increases resistance. You are conflating different type of resistance… If you understood that an induction motors speed is determined by frequency and poles, not voltage, this would all make more sense…

[@GH-oi2jf]

There is one error in the "Terms" slide. "Watts" are power, which is the rate of doing work. "Energy" is equivalent to "work" and is power integrated over time.

[@TacoDaddy-mr8ig]

If u have one thing in a circuit, it is a series circuit because it has one path... 😮

[@matthiaschimza8595]

Is it true that in alternating current electricity comes from the grid through the live wire and go back via the neutral wire. But why do you have a spark(short circuit) when you directly connect live and neutral, isn't the electricity supposed to just alternate between the wires? Just wondering

[@MrDmadness]

There's no load. In order to have a circuit a load is required or else wires burn ( if there was no breaker )

[@EarlHayward]

The neutral wire is only neutral in relation to L1 and L2; which is why we have split single phase, not two phase as some people incorrectly assert. You can still get shocked from the neutral…

[@justinkrohn-dh8di]

On the test, would you assume to derate for conduit fill? 3 or more conductors?

[@ryanisaacson118]

We are electrion in the 20s its 2022

[@Lootworks]

This is heavy

[@nathanj.williams1955]

Could you explain a circuit overload please. Since increased resistance from over "load" should decrease amperage then why does the breaker trip?

[@TacoDaddy-mr8ig]

I'm not 100% sure what u are asking but, if u have an overload than the breaker would trip. So if u have a breaker rated for 20 amps and u overload it( putting to many loads on that breaker) and it begins to draw 20.5 amps or 21 amps, that the breaker would trip...

[@nathanj.williams1955]

@@TacoDaddy-mr8ig Thank you for taking the time for that question. More what I meant is this; In ohms law if you increase resistance then you've decreased current, so if an overload is excess Resistance then wouldn't that decrease current and the breaker would never trip?

[@TacoDaddy-mr8ig]

@@nathanj.williams1955 actually with an overload, the resistance would go down and a lot more current would flow therefore the breaker would trip.. think about the word ' overload ' OVER(to many) LOAD ( HAIR DRYERS) so, if u have to many loads, than the current draw will increase and cause the breaker to trip..

[@nathanj.williams1955]

@@TacoDaddy-mr8ig on a parallel circuit an overload would decrease Resistance which I think I understand now. Thank you very much man for helping me there.

[@paulisaaksohn9179]

Overload means your load is drawing too much current due to a technical malfunction. This means we are talking LESS resistance, which ia why more current is suddenly able to flow through the load. Overload is NOT increased resistance. Think of it this way: if the system is functioning properly all its parameters (Voltage, Current and Resistance) are well-balanced. When this balance is disturbed this is when things go wrong. Overcurrent means increased current due to strain or voltage drop (in motors, pumps, etc.). More current is drawn and is able to pass through the appliance because resistance has dropped and it should not otherwise have happened. Hope this makes it a bit clearer.

[@whateven4675]

Holy shit that is some rockstar teacher behavior I live.

[@jackjohnson2309]

I have to ask: WHY does electrical resistance drip if physical resistance increases? I understand the inverse relationship between resistance and current, but I don’t get how physical resistance decreases electrical resistance. Edit: I get the example given with the heat strip, but the example of rough bearings slowing a motor or something similar, I don’t get how that reduces electrical resistance.

[@GH-oi2jf]

A spinning rotor in an energized motor generates back-EMF in the stator, which has the effect of lowering the voltage that the motor "sees," or you can think of it as increased electrical resistance. This why there is a current surge when a motor is turned on. The current drops as the motor approaches its working speed.

[@glenforehand]

“Something isn’t happening that should be happening” is an open, but what about voltage drop? Is that not as much of an issue in a/c circuits as it is in d/c?

[@johnnyreb280]

So,...If I understand the question sir,..while voltage drop is an inherent phenomenon in both AC and DC circuits, its manifestation and implications differ significantly between the two. AC circuits present unique challenges due to impedance, reactance, skin effect, and proximity effect, making voltage drop a complex consideration in AC system design and analysis, particularly in high-frequency applications and power transmission systems. Understanding these nuances is essential for optimizing circuit performance and ensuring efficient power delivery in AC systems.

[@glenforehand]

@@johnnyreb280 thank you for your explanation. Voltage drop testing as I’m describing on a DC is using a voltage measurement at the load. The result of a voltage reading lower than designed would reveal the presence of resistance in the circuit that should not be present if the circuit is in tact. For example, if I’m testing at a vehicle headlight and I’m measuring less than battery voltage, assuming the design calls for that, I might suspect corrosion in a connector. Is such a testing method appropriate with a AC system we might find in a commercial building or even a home? I’m curious if it might help speed up diagnostic testing on equipment specifically if one were to record voltages themselves while the equipment was operating correctly if that information was lacking. I see a lot of part swapping and guessing in a place I frequent. It seems wasteful in both parts and labor. One instance a board was suspected and was going to be ordered because a fuse was blowing. I quickly inspected the circuit and found a short. The board was expensive and unnecessary. I inquired about the voltage drop testing and it hadn’t been heard of. The subject of PWM came up because it’s used in the newer equipment and I asked which scope they use. Same result, I explained PWM too as it was unknown. It was odd to me because I see all the above daily in automotive diagnostics. That led me to the question I asked above. I know very little about AC systems and was curious if the nature of the AC system somehow rendered the test unreliable. I don’t see how it would be though on a piece of equipment that has fixed loads.

[@EarlHayward]

Alternating current has dozens of voltage drops per second, research root mean squared and you will understand… But, that type of voltage drop is not what you were really asking about… Yes, there is voltage drops in AC, but you generally wind up with other issues before you would notice the changes from a power drop - like smoke or fire from overheating wires…

[@glenforehand]

@@EarlHayward thanks I appreciate your time answering.

[@Parabellum-X]

7:28 I thought that if a motor was seized, that would INCREASE resistance in that circuit, therefore reduce the current draw?... 🤔

[@HVACS]

Decreased resistance = higher current Look at ohms law

[@Bluesonofman]

Also Direct Lets you know you fucked up while Alternating kills you

[@Huyautomation2901]

8:40 I have to reject your opinion because saying who said Amp is the killer is silly. Amp kills you directly. Vol is a factor but still not a killer in a main way.
