Let's apply Kirchhoff's voltage law and Kirchhoff's current law in solving a two-loop circuit!
KCL states that the total current entering a node = total current exiting a node, charge conservation!
KVL states that the total voltage change in a closed-loop = 0, energy conservation!
Using these laws, we build equations for current and solve them algebraically.

That's an error, thanks for pointing out. It should have been -23. But the final values are correct, phew!

The directions of the Currents in different loop as considered by is wrong because the flow of current in any circuit is always from Anode (The positive terminal) to --> the Cathode (The negative terminal) | Your explanation just made this law look like a Simple one. Thank you sir 😃✨👍🏻 #SaveSoil

Based on the direction of the arrow or rather the current flowing, current always flows through resistors from the + terminal to the -- terminal so that's why

Why I2 current move to upward direction 2:28

@theartistinaction9334 10 ай бұрын

thats only an assumption you make. if you look at it like this the 32v supply is more stronger than the 2v supplies, which would automatically make all currents flow from the positive side of the 32v battery. Which would make I1 and I2 flow in anti clockwise direction and then split at the junction and I1 will go leftwards and I2 downwards , then the currents will be positive. But we assumed current in right and top directions which is opposite to the original flow, thus we got a negative current.

Sir why we are adding at 3 ohm resistor because resistor reduce voltage again you will say sign convention but it does not convince mee sir please explain🤔🤔🤔

@KhanAcademyIndiaEnglish 3 жыл бұрын

Can you clarify the time in the video that you are referring to? Here is one way to think of it. Current direction through the resistor is always from high potential to low. So, throught a resistor, potential drops in the direction of the current. Which means potential increases as you go through the resistor in the opposite direction of current.
