1 of 1

Understanding +4 | -1

Assertion: Through the same current flows through the line wires and the filament of the bulb but heat produced in the filament is much higher than that in line wires.

Reason: The filament of bulbs is made of a meterial of high resistance and high melting point.

View answer and explanation

Correct option: A

If both Assertion and Reason are true and Reason is the correct explanation of Assertion.

Option A is correct because the heat produced is proportional to the resistance, and the filament has a much higher resistance than the line wires.
