JEE PHYSICS MCQ: CURRENT ELECTRICITY

1 Medium

1 of 1

Analyzing +4 | -1

Assertion: When current through a bulb is increased by

2 \%

power increase by

4 \%

Reason: Current passing through the bulb is

\propto \frac{1}{\text { Resistance }}

View answer and explanation

Correct option: B

If both Assertion and Reason are true but Reason is not correct explanation of Assertion.

Option B (If both Assertion and Reason are true but Reason is not correct explanation of Assertion) is correct because the assertion is true based on the power formula, and the reason is true but doesn't directly explain the 4% power increase.
