## Homework Statement

In the figure below, what is the potential difference

*Vd*-

*Vc*between points

*d*and

*c*if E1(of 1st battery) = 4.7 V, E2((of 2nd battery) = 1.4 V,

*R*1 =

*R*2 = 11 Ω, and

*R*3 = 6.7 Ω, and the batteries are ideal?

## Homework Equations

V= IR

## The Attempt at a Solution

I used superposition in order to find the current at R2 which leads to V2 = I2R2.

I separated the circuit into two circuits , each with one battery and its own calculations then I added them together , but the final answer seems wrong for an unknown reason....
