Kirchhoff's Current Law (KCL) Explained

In our previous lesson, we examined Kirchhoff's Voltage Law. In this video, I will explain the Kirchhoff’s Current Law, which is as important as it is for us to analyze electrical circuits and one of the most important issues we need to know. Let's try to learn this law through the circuit here.

Many thanks from a middle-aged man who is learning electronics physics which is long due in his life!

My teacher did not explain this formula so easily durig engineering but you are much better.

[@eeapplications]

I try to explain in a way that everyone can understand. Glad if it was useful. I'm glad you liked it 😊

[@Davis38]

Thank you so much for making these videos, they really help me in repeating basic must-know concepts

I'm so glad it was useful. Thank you 🙏

All laws of physics are quite simple. But it is the tendency of academicians to screw it and make it difficult to understand and apply.

[@eeapplications]

Glad you like it ☺️🙏

No. It's that the students are not very intelligent. This is the problem with electricians. They have trouble understanding the basics of electrical circuit theory. But the basic principles are actually quite simple. But these principles employ some mathematics and that is what most student electricians can't handle. They left school with very few exam passes, and then the electrician courses have no pre-requisites, so no minimum knowledge of maths is required. So when it comes to students understanding these principles in class, they struggle.

[@edwinlipton]

@@deang5622 with all due respect to your views. In the U.S.A., we have electricians, electrical Licensed contractors and electronic engineers and technicians. Quite different in there trade and applications of there aquired field of choice. "I" am a retired Master Contract construction Plumber. The people at thee other end of sewage discharge are civil engineers. We both handle pipe, but are at different levels. My birth father was a line man,, he worked the high power lines before they dropped into sub station transformers and distribution lines to houses and buildings where; electricians with there "SPEACIALIZED" training was applied. All of them worked with wires and applied voltages and amps too there preferred ability of knowledge. No different for family practitioners vs. Oncologist.

These as well as ohms law are so important that if not discovered things would be so different today.

[@ANJA-mj1to]

Great way to give the depedence of maxiumum absorber temperature on the concentration. For the absorptance the value one independent of the wavelet is assume then importance is on The Kirchhoff's law states that every wavelenght the absorptance is equal the emmitance of a surface. So this is brilliant way to bring on the light Kirchhoff's law like very good emitter of thermal radiation.

I don't see why you would ever want to use components in parallel unless you wanted to get some really specific value or something. But then again I'm still learning.

[@Swenser]

Max power rating of single part is one reason.

I detested Kirchoff’s Law at Uni… it didn’t help that the lecturer and I didn’t get along either. This has helped me understand the Current Law, now I’m going to find your Voltage video… thanks!

[@andrewcherowbrier329]

when you subsitute numeric values into the formulae, the I, (current *") looks like 1. ("one point) which is not helpful. Its an unfortunate similarity between the 1 and the I in the chosen fiont.

[@eeapplications]

Thank you for your alert. I will be more careful when writing formulas 👍

[@opecons]

Hi..what's the answer of this? Three resistors ABC are connected in parallel. The resistance of A is 6 ohms and that of B is 5 ohms. The resistance of C is adjustable. The current to the circuit is 4 amperes. To what value should the resistance of C be adjusted in order that it may take 1.5 ampere?

[@YoutubeSupportServices]

It shouldn't matter what it's adjusted-to! If the circuit is already "taking" 4 amperes then it will "take" 1.5 amperes and also decrease heat generation by approximately 66.6%, unless of course after lowering the current it was then placed into an oven along side a delicious pizza that was being baked at 350F for 30 minutes. In this case we would then need to know which station the train left from at 2pm so Timmy isn't late for his 3rd gender-reassignment bottom-surgery....

[@Swenser]

What's the law called that states sometimes the laws are going against themselves. Like when you flick the switch , each component tested good, but still no go.

All materials can be explained mathematically. Even the ⚛️ ⚛️⚛️⚛️

[@lynnashley6247]

Your images suggest a duracell, which unfortunately is well known for its extremely damaging leakage. Maybe better to use the rabbit or a generic.

[@eeapplications]

Pictures are representative only.

[@deang5622]

What does the type of battery have to do with the principle? Where do you see in the mathematical equation reference to any particular type of battery? You should be smart enough to recognise that the manufacturer of the battery is totally irrelevant. In actual fact, using a battery image is not the right way to represent an electrical circuit in the first place. It should be fine with proper electrical circuit symbols which are standardised, and the battery is represented by two parallel lines of unequal lengths.

About as clear as mud but I now how pigs fly.🍋

[@deang5622]

If it is as clear as mud, then I would suggest to you that you don't have the required physics and mathematics background and possibly intelligence to understand it. My advice to you would be to stay away from any educational course on the topic of electricity as you're not cut out for it But seriously, any 16 year old kid should be able to get their head around this. The science and maths involved is school level. Electricity doesn't get any simpler than this. This is as easy as it gets. If you're of average level of intelligence and attended science classes in school, you shouldn't be struggling. The way the presenter has presented it is actually very good. He has done a good job.

[@martinkuliza]

1. Why are you here in the first place ? if you are here it means you must have some fascination for the basics of electronics and electricity 2. How old are you ? I have a 14 year old Nephew, he understood this perfectly 3. Why is it unclear, What makes it unclear to you ? The thing about electricity and electronics is it starts simple as simple can be, it starts with "Here is a wire" and everything goes from there , one concept building onto another . if something is unclear YOU GO BACK TO THE STEP THAT YOU UNDERSTOOD CLEARLY You then learn again how to get from that step to this step if you still can't , you ask someone who is familiar with it to explain it to you (i'd be happy to ) Ultimately these things are simple and even at the higher levels , the step from one concept to another IS ALWAYS SIMPLE (given the current level of knowledge for that step) so you are never without means of how to understand in very rare circumstances people do not understand but this only happens if 1. Someone has a mental illness that prohibits normal brain function and learning ability 2. someone is lazy 3. someone doesn't really want to learn or doesn't have a keen interest in the subject but if you are keen on the subject and don't have a learning disability , Learning this should not be a problem Granted sometimes IT'S THE TERMINOLOGY that fucks you up, I get that ! so.... WHAT PART OF THIS IS CLEAR AS MUD ? allow me to clear that mud up for you ?

Battery voltage will sag under the load so won't be 9v lol. Better to show a straight voltage supply.
