Question

When electric current is passed through a wire, the amount of heat produced in a wire depends upon _____.

I. Length

II. Thickness

A Only II Correct Answer Incorrect Answer
B Both I and II Correct Answer Incorrect Answer
C Only I Correct Answer Incorrect Answer
D Neither I nor II Correct Answer Incorrect Answer

Solution

The heat generated in the conductor depends upon its resistance. The resistance of the wire further depends upon the length and thickness of the wire. So both the length and thickness of the wire will affect the amount of heat.
