Homework Statement
We need to find I1,I2,I3 (current through all the three branches)
Homework Equations
I know that if emfs *of same value* are connected in parallel,then they can be replaced with a single emf of that same value,and that's where the problem comes in.There are 3 emfs,all of different values connected in parallel.
As far as the rest of the curcuit goes,
▪KVL (Kirchoffs Voltage Law):Sum of potential drops across a closed loop is zero
▪V=I.R
▪Voltage difference across conducting wire=0
The Attempt at a Solution
You'll forgive me if the diagram's a little crowded.Basically,I assumed potential to be 0 at a point for reference purposes, and then labelled all other parts of the circuit corresponding to that.
Now,as I said in the last line of the previous section,
▪Voltage difference across conducting wire=0
That means that V(at A)=V(at B)=V(at C)
(Assumin I1 as x,I2 as y,I3 as z)
That would give us our first set of equations:
8-x=9-2y=10-3z
Now,applying KVL in loop ABEF,
8-(8-x)+(9-2y)-9=0
However,on solving these equations,I ain't getting the right answer.
Help appreciated..
