The internal resistance of a battery is:
Correct answer: B. In series to the external load
- A. In parallel to the external load
- B. In series to the external load
- C. Not connected to the external load
- D. Zero
Explanation
The internal resistance of a battery is in series to external load. Hence option B is correct.

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.
