The energy supply being cut-off, an electric heater element cools down to the temperature of its surrounding, but it will not cool further because

A

supply is cut off

B

it is made of metal

C

surroundings are radiating

D

element and surroundings have the same temperature.

Text Solution

Verified by Experts

The correct Answer is:
D

When element and surrounding have the same temperature. There will be no temperature difference, hence, heat will not flow from the filaments and its temperature remains constant.
