Homework Statement
Calculate the drop in potential across each resistor:
Homework Equations
V = IR
Kirchhoff's circuit laws
The Attempt at a Solution
V1 + V2 has a current of I1 that goes through R1 and R3 which are in a parallel circuit. V3 has a current of I2. The two current combine so they go through R2 with I3 (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.
