We are asked to solve for I. I found I = -4 Amps.
I want to verify my answer using KVL in the bottom left mesh
The Attempt at a Solution
I follow the convention: voltage drops are positive, which means that the first sign I hit is the sign of the voltage. Starting at the 8 ohm resistor:
- 8*(-4) + ( ????? ) - ( ?????) = 0
I am confused because we usually apply KVL using the voltage drops/rise between elements. For the current source and the 2 ohm resistor, I have the node voltages between these elements. Therefore, I don't know if the current source is + (v2 - v1) or - (v2 - v1). Same thing for the 2 ohm resistor, I hit the - sign first, but is it - (v2 -0) or - (0-v2) ????
I am a little bit confused.. thank you very much
