A storage battery with emf `epsilon=2.6V` loaded with an external resistance produces a currnet `I=1.0A` in this case the potential current `I=1.0A`. In this case the potential difference between the terminals of the battery is `V-=2.0V` now

Options

A. The thermal power generated in the batery is 0.6 W
B. The power developed in the external resistance is 2.0 W
C. The thermal power generated in the battery is 0.5 W
D. the power developed in the external resistance is 4.0 W

Answer

A, B

Explanation

Let, internal resistance of the cell be r, then `V=epsilon-ir`, where `i` is the current in the circuit. We know that thermal power generated in the battery. `Q=i^(2)r`
