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?
