Homework Statement
Suppose that a battery of emf E and internal resistance r is being recharged: another emf sends a current I through the battery. Why rate is electrical energy being converted into chemical energy?
Homework Equations
P=EI-I^2*r
V=E-Ir
I know that since it is being recharged, the current flows in the reverse direction (positive terminal --> negative terminal), however, I'm not sure how to go about doing this.
