The resistance of an incandescent lamp ...

The resistance of an incandescent lamp is

A

greater when switched ON

B

smaller when switched ON

C

greater when switched OFF

D

same whether it is switched OFF or ON

Text Solution

Verified by Experts

The correct Answer is:
D

We know that resistance of an incandescent lamp depends upon the nature of the material used, its dimensions and physical conditions .
`:.` It doesnot effect whether the lamp is switched OFF or ON or in other words the resistance remains the same whether the bulb is switched OFF or ON.
