1. The problem statement, all variables and given/known data What is the current in this circuit: http://img802.imageshack.us/img802/4646/8ekh.png [Broken] 2. Relevant equations All potential differences in a closed portion of a circuit must add to 0. Terminal Voltage = EMF - I x internal resistance. 3. The attempt at a solution I do not know how to do this, the answer says the current is 0A. I have no idea why.
