Hi,

I’m having some trouble with Kirchhoff's circuit law problems regarding two batteries in the circuit. I've attached a crude picture of a problem i picked to understand whats going on.

So for the bottom loop I have

5V - 5v = i1 - i2

0= i1 – i2

The top loop I’m coming up with

5 = i2 -2(i1+i2)

5= i2 -2i1 -2i2

-1(5 = -2i1 -i2)

So I’m left with

5 =2i1 +i2

0= i1 – i2

5=-2i1

0=- i1

5=-3i1

5/-3 = i1

But, I think this is wrong.
