Problem 3.192

A storage battery with emf $\mathscr{E}=2.6 \mathrm{~V}$ loaded with an external resistance produces a current $I=1.0$ A. In this case the potential difference between the terminals of the storage battery equals $V=2.0 \mathrm{~V}$. Find the thermal power generated in the battery and the power developed in it by electric forces.
