Physics · Current Electricity
Consider the following two statements regarding a battery: S1: Potential difference (V) across the terminals of a battery may either be equal to or less than the emf (E) of the battery. S2: During discharge of a battery, potential difference (V) across two terminals of the battery is V = E - ir; r is the internal resistance of the battery and i is the current through it. Choose the correct option using the code given below:
- 1S1 is true but S2 is false.
- 2S1 is false but S2 is true.
- 3S1 and S2 both are correct and S2 is the correct explanation of S1.✓
- 4S1 and S2 both are correct but S2 is not the correct explanation of S1.
Correct answer
S1 and S2 both are correct and S2 is the correct explanation of S1.
