Question

Assertion: The same current flows through the line wire and filament of the bulb

but heat produced in the filament is much higher than that in line wires.

Reason: Filament in bulb is made of a material of high resistance and

high melting point.

​

Answer 1

Explanation:

assertion is write but the reason is not the correct explanation of assertion

Answer 2

Explanation:

As filament of bulb and line wire are in series, hence current through both is same. Now, because H= i²rt/4.2

and resistance of the filament of the bulb is much higher than that of line wires, hence heat produced in the filament is much higher than that inline wires. Hence Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
