Mesh Analysis for Circuits Explained

- This tutorial introduces Mesh Analysis and explains how to use it to solve unknowns in circuits. I find it helpful to label on unknown branch currents before starting the problem, and then substituting the mesh currents in later. This reduces the chance of getting some terms with the wrong sign, but is not a necessary step, as most books will skip that part. Mesh analysis can be used to solve circuits with multiple loops, and in a later video, we'll go over some examples of supermesh analysis as well (we need to do that if there is a current source between two mesh currents).
This video is part of a full free course on electric circuits. The course covers DC circuits, circuit laws, current & voltage sources, series & parallel resistors, nodal analysis, mesh analysis, and AC circuits.

Thanks mate, the way you showed to list all the currents first then putting in terms of loop currents makes alot of sense
Nice video shot, keep it up, thank you for sharing :)
thank you, sir, that explanation would help me a lot.
thank you, very clear explanation
For some reason ur voice is really calming eventho im clueless and have a exam in 2 days…
Good luck!! More at engineer4free.com/circuits
This is so much more fun with phaser impedance elements
😅
What if we are finding the current from I1 to I2
I got -.5 amps
I used the rise drop convention for i1
this is very helpful, how would you explain mesh analysis for a high pass filter?
Perfect
Voltage across 1 ohm (0pened) = ??
Wrong
Ia is 4.5a
Ib is 1.5A
Ic is -6A
Sir what if i take mesh current in anticlockwise direction
It will work, but just make sure you follow all the rules.
tnx
Sir how do we mark the signs if the source is in the middle of the circuit
late answer but that is called a supermesh.
Pls I have some questions and problems can help me solve them
What's the difference between mesh and kichofs law

Mesh analysis is a way to solve circuits USING Kirchoff's loop law. Technically, you are just using the loop law but the whole procedure that you do in this video is called mesh analysis because its commonly used method
thanks to you
Welcome!
uhm why the voltage in kvl become - sign ?
It looks like he was using the node he was entering to determine the sign. Because not only was the voltage switched when passing through the battery, but the voltage rose through the resistors. It's ASC (as opposed to the more common PSC), and it came out of left field, but I suppose if applied consistently, it's fine. But I agree, it's not my go to.
Simply because he used the sign convention that if you go from - to +, which you encounter the negative sign first, you treat it as negative. And if you go from + to -, like on resistors, you treat it as positive.
Wrong ?
Elaborate
@@michaeljordan5630agreed, it would be nice for those that are saying is wrong to explain what is wrong and perhaps also how to do it..
It is ❌❌❌❌ wrong
What is your I1?
Why
Let it be wrong let it be right but I’ll ask you when last did you see $1m
I have never met someone who does KVL the way you do, it threw me off. I was always taught KVL: VS - VR1 - VR2 .... - VRn = 0
Too close to mic dude. Didnt sign up for ur saliva noises
