Statement-1: Potential difference across the terminals of a battery can be greater than its emf.
Statement-2: When current is taken from battery, (Symbols have their usual meaning).
Statement-2: When current is taken from battery, (Symbols have their usual meaning).
View answer and explanation
Correct option: B
Statement-1 is true, Statement-2 is true, Statement-2 is not the correct explanation for Statement-1
Option B (Statement-1 is true, Statement-2 is true, Statement-2 is not the correct explanation for Statement-1) is correct because the potential difference can be greater than the emf when the battery is being charged, and Statement-2 describes the voltage when the battery is discharging.
