given the following:
http://lh6.ggpht.com/_H4Iz7SmBrbk/Sg04JIIg9vI/AAAAAAAAA-o/xDycbG90Gmc/s720/C.jpg
and given that
ε1=3V
ε2=2V
R1=1Ω
R2=2Ω
R3=3Ω
i am asked to find the current flowing throiught R1,R2, R3
what i did was
I3=I2+I1
I1R1-I2R2=ε1
but i am short of one equation to solve this, what i would like to do is somehow find R12, as an the sum of R1 and R2, but my problem is that i have ε1 between them and i have no idea how to tackle this,
had ε1 noot been there i would have said R12=(1/R1+1/R2)-1 and then i could make a third equation using this.
how can i solve this?
