(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Calculate the drop in potential across each resistor:

2. Relevant equations

V = IR

Kirchhoff's circuit laws

3. The attempt at a solution

V1 + V2has a current ofI1that goes through R1 and R3 which are in a parallel circuit.V3has a current ofI2. The two current combine so they go throughR2withI3(I1 + I2)

So I came up with:

I3 = I1 + I2

(V1 + V2) - I1*[(1 / R1) + (1 / R2)]^-1 - R2*I3 = 0

I'm not sure if the above is right or how to find the third equation. Any help is appreciated.
