Question

The potential difference across the terminals of the battery when it is not connected in the circuit
is
(A) equal to its emf
(C) smaller than its emf
(B) greater than its emf
(D) zero​

Answer 1

Answer:Equal to Emf

Explanation:As no current flows through battery due to open circuit, no potential drop occurs across internal resistance

of battery. So voltage across terminals= emf of battery

Answer 2

Explanation:

smaller smaller then it's EMF
