Terminal potential difference of a cell
Correct answer: B. Decrease with increase in internal resistance
- A. Increases with increase in its internal resistance
- B. Decrease with increase in internal resistance
- C. Is independent of its internal resistance
- D. None of these
Explanation
As; E= IR+IrIf internal resistance increases, Ir increases and IR=V= terminal potential difference decreases because E=emf of the battery is constant.

About Current Electricity
Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
