When same current passes for same time through a thick and thin wire:
Correct answer: C. More heat is produced in thick wire
- A. No heat is produced in wire
- B. More heat is produced in thin wire
- C. More heat is produced in thick wire
- D. None of these
Explanation
The correct option, C) More heat is produced in thick wire, highlights that when the same current passes through both thick and thin wires for the same amount of time, the thick wire produces more heat. This is because the thick wire has a lower resistance due to its larger cross-sectional area, leading to less heat production compared to the thin wire.

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.
