A portable battery supplies electricity to an external circuit for 2 hours. The voltage across the terminals of the battery is observed to increase from initial voltage of 5V to 10V (linearly) and the current increases from 1A to 2A (linearly) in 2 hours.
Sketch voltage, current, power versus time graphs for the case.
