## Homework Statement

We wish to find Va-Vb given that R1 = 1000 ohm, R2 = 2000 ohm, R3 = 3000 ohm and emf = 10v.

## Homework Equations

??

## The Attempt at a Solution

I started by trying to simply the circuit but couldn't do so because of R3.

then i decided to add potential differences and currents.

Let the current from

DA = I1

AC = I2

AB = I3

CB = I4

CD = I5

BD = I6

loop: ACDA

-I2R2 - I3R1 + emf = 0

loop: ACBDA

-I2R2 - I4R3 -I6R2 +emf =0

loop: ABDA

-I3R1-I6R2+emf =0

current sum

I1 = I2+I3

I2 = I4+I5

I6 = I4+I3

I1 = I5+I6

And i am not sure how to go from here?

Do i put them in a matrix and get rref then backtrack?
