When different resistors are connected across terminals of battery:
Correct answer: E. Its emf remains same but terminal potential difference changes
- A. Both emf and terminal potential difference gradually changes
- B. Both emf and terminal potential difference changes
- C. Its emf changed but terminal potential difference remains same
- D. Both emf and terminal potential difference remains same
- E. Its emf remains same but terminal potential difference changes
Explanation
When different resistors are connected across terminals of battery their emf remains same but terminal potential difference changes. So option E 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.
