Question

I'm coming up with:

V1 - R3*I3 - R1*I1 = 0 and -V2 - R3*I3 - R2*I2 = 0 for the junction rule and I1 - I2 = I3. Am I right or wrong, and if wrong, could you please explain what the correct answer is? Thanks

What are the equations for the junction rule and the loop rule for loops febaf and debcd? I'm coming up with: V1 - R3*I3 - R1*I1 = 0 and -V2 - R3*I3 - R2*I2 = 0 for the junction rule and I1 - I2 = I3. Am I right or wrong, and if wrong, could you please explain what the correct answer is? Thanks

Explanation / Answer

for the loop febaf

V1 - I3R3 - R1I1 = 0

for the loop debcd

V2 - I2R2 + I3R3 = 0

so you are wrong in the loop debcd.

For writing the loop equation lets move in anticlockwise direction in the loop debcd. Then for R3 the sign will changes because we are moving opposite to the direction of the current. rest part is correct.
