Problem:
"A 12.0 V battery with an internal resistance of .02 Ohms is used to charge a battery with an emf of10.5 V and an internal resistance of .15 Ohms. What is the charging current?"
Question:
I'm pretty much stuck on the set up of this problem. I know how to find the current if there was some resistor and these were hooked up in parrallel, but the way the problem is worded it makes me think these are simply just in their own loop. More over I'm not sure how I would set this problem up if they just created their own loop... Any help would be appreciated.
PS: To charge a battery the current across the battery points from negative to positive right?
