## 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.
