Let's Talk About PARALLEL Circuits: Voltage, Current, Resistance, and Power

[@electricianron_New_Jersey]

Not bad, Dustin! I'm an instructor at the IEC in New Jersey and I have to say any electrician taking the time to watch/ study this video is an electrician well on his way to becoming a very valuable asset to society. Cheers!

[@Kvalulf]

Thanks for this. The professor in teaching the class spent a total of 5 minutes going over this flipping back and forth on various power point pages. I've learned more about this subject from youtube videos now.

25 year commercial/industrial electrician here. I'm also an instructor for the ABC of Iowa electrical apprenticeship program. Along with Eugene Khutoryanski's physics videos, I've used your videos extensively for my class (it keeps them from having to hear me drone on four hours a night every week). Because I'm also a nerd when it comes to the theory, I'd love to see you do videos on inductive and capacitive reactance and combine those with resistive circuits to throw in a lesson on power factor with it. As important as Code is (we use the Mike Holt curriculum); knowing it's necessary to be able to navigate the NEC to pass the journeyman exam - I think there's been some lost emphasis on the theory. I do a LOT of troubleshooting in the field. I think knowing not only how electricity behaves, but WHY it behaves the way it does is critical to advancing in one's career.

Thanks for the video, nice to refresh on the basics sometimes!

[@machintoshfc]

If these are basic, then I need to crawl.

[@DJack34]

I can’t wait to get to this part of the job, this kind of stuff excites me.

Another GREAT video, thanks! When I first saw Parallel Total Resistance and the reciprocals, I started doing the math in my head with the Least Common Denominator (LCD) and you referred to this approach in your video, whew, good to know that I am not the only one😁. I would have liked at the end when you were doing Power if you had used the Pt=E²/Rt formula as a proof, where 50²/1.3333 = 2,500/1.3333 = 1875 W. Love the Video, Great Work, keep it up!

Finally got around to watching this, great vid.

Lunch time is parallel to when the boss wants to rush the job. Facts

Not when you are with a good union contractor.

The resistance to the bosses pressure is greater than the resistance to fill my belly!

[@Jordanslifts]

What an underrated video, and channel. I truly believe this is why KZbin was made. Thank you very much

[@mrsamba8151]

Thank you

[@damianrodriguez2205]

As more branches are applied to the circuit resistance lessons due to having more paths to flow through which means resistance goes down, and current goes up.

[@jeremybrandt5779]

Is residential wired in parallel or series?

[@alexcoble8819]

Thanks for the help, super useful. Do you ever regret that spider tattoo?

[@FunInVa]

You should add this into your theory album.

[@james402windexman]

What causes series circuits and parallel circuits to be different? Why does the different schematic cause one to drop in volts and the other to drop in amps? Also what's more common in basic households parallel or series? And in what circumstance would you choose one over the other?

[@sethgodfrey9182]

The difference is the flow of the current in each circuit. For series circuits the current only sees one path with one total resistance, therefore the flow of current does not change throughout the circuit. But the voltage has to be dropped to zero by the time it makes it back to the source. So each load drops a specific amount of the voltage which is dependent on the resistance of that load. Parallel circuits still work the same way however, it has branches so instead of seeing one path in the flow it has 2 or more depending on the amount of parallel branches. If each branch only has one load it has to drop all of the voltage, that divided by the resistance gives you the current in the branch. But, when each branch merges back together the current adds together. The current leaves the source with the total amount of current, each branch it hits some of if it breaks off. As the branches merge on the other side they combine again and head back to the source as the original total. As far as circuits in houses to my knowledge most circuits would be parallel unless they have only one load. Sorry for the long reply that was the best way for me to explain it. I hope it helps.

[@james402windexman]

@@sethgodfrey9182 that was immensely helpful, long reply necessary to convey all that. Thank you!

Cool video Dustin keep them coming back lol 😢😂❤🎉

[@JamieBroussard-d7c]

why would a varistor be put in parallel with the input power of an LED driver? It seams that it will not stop any power from flowing to the driver because it is in parallel.

[@tedlahm5740]

We did the math in REVERSE. Should of done the current for each resistor first? Then the PROOF math for the voltage?

[@cleberandrade]

He's just thrown formulas. You must use first that one that has all available measures. If R and E are known, you can start calculating I. If I and E are known, you can start calculating R. If everything is known, you can call it a day.

[@brrr8963]

Hell, yeah

[@ChaunceS]

I'm assuming power = wattage?

[@rty1955]

Be careful when describing "power" or wattage. Power calculations are DIFFERENT for AC than it is for DC. You can use DC formulas for an APPROXIMATION of power, but its not the correct formula. With AC not only do you have voltage, current & resistance, but you have FREQUENCY and with AC circuits, resistance is called IMPEDANCE. This is why there are Electricians & Electronic Engineers. Electronic Engineers must understand way more than Electricians.

[@willfergusson724]

I guess why there is a difference between Volt-amps and Watts ?

[@deang5622]

The issue isn't the frequency as that is always fixed in mains electrical installations, the issue is the phase angle for the load impedance.

[@deang5622]

​@@willfergusson724The difference is because the voltage and current are not in phase with each other

[@Electroguy74]

Is "amperage" a word??

[@-doughnuthole-]

Yep

[@stanleybernard6958]

Ran into parallel circuits on tug boats has anyone come across one in the residential field yet

Hello . Im writing to you because you are a eletrican plus you use milwakuee tools to. Now i got a milwakuee charger butned down resistor . is 5 band silver yellow black brown green . The r 8 . which one is the value. thank you
