Question

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 then that in line wires. <br> Reason : The filament of bulbs is made of a material of high resistance and high melting
​

Answer 1

Explanation:

As the filament is like a solenoid( a coil with rings), the current passing through the filament may have more current than the line wires. But we have to note that current entering the line wire and filament are same while the current flowing in them are different due to disimilar path they flow.

If there is more current flow then the body gets more heated thus produces more heat energy and light energy.

Thus both the statements are correct but not correct reason.

Answer 2

Answer:

Option a (reason and Assertion is correct
