Learning Goal: I’m working on a physics question and need the explanation and answer to help me learn.

A battery has an open circuit potential difference of 6 V between its terminals. When a load resistance of 60 ohm is connected across the battery, the total power dissipated by the battery 0.4 W. What would be the load resistance R, so that maximum power will be dissipated in R. Calculate this power? What is the total power supplied by the battery when such a load is connected.
