(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

trrttA battery has an emf of 15.0 V. The terminal voltage of the battery is 11.6 V when it is delivering 20.0 W of power to an external load resistor R.

(a) What is the value R?

(b) What is the internal resistance of the battery?

2. Relevant equations

3. The attempt at a solution

I'm sure how to start this problem. I'm sure I get rolling if I can just get some momentum started. Please Help.
