JEE PHYSICS MCQ: CURRENT ELECTRICITY

Analyzing +4 | -1

Assertion: As temperature of a metallic current carrying the wire is increased, its resistance increases.
Reason: Decrease in temperature results in a decrease of electric field strength, along the conductor so that the current reduces.

View answer and explanation

Correct option: C

If Assertion is True but the Reason is False

Option C is correct because the assertion is true (resistance increases with temperature for metals), but the reason is false (decrease in temperature does not directly cause a decrease in electric field strength).
