Find the magnitude of the current in the 14V cell.

Answer in units of Amperes.

2. Relevant equations

Kirchoff's junction & loop laws:

I_{1}= I_{2}+ I_{3}

ƩΔV = 0

V = IR

R_{series}= R_{1}+ R_{2}+ ...

1/R_{parallel}= 1/R_{1}+ 1/R_{2}+ ...

3. The attempt at a solution

At first I assumed that the current inside an ideal battery is 0 amps. But it appears that is incorrect. I've been going over my notes and looking through my book for a while now, but I have had no luck in finding out how to find the current in a battery in a multi-loop circuit. I have also tried setting up 2 different loop equations but those were wrong too. I know that the value has to be positive because it wants the magnitude. I'm not going to give up on this but I do need help from a reliable source. Any help is welcome.
