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