Answer 2

$\color{darkblue}\underline{\underline{\sf Question-}}$

Out of 60 W and 40 W lamps, which one has higher electrical resistance when in use

$\color{darkblue}\underline{\underline{\sf Answer-}}$

We know that ,

$\color{violet}\underline{\boxed{\sf P = i^2R}}$

Power is directly proportional to Resistance

i.e. ${\sf Power \: \; \: \propto\:\:\: Resistance}$

If power will increase then resistance will also be more.

Therefore , here 60 W lamp will have higher electrical resistance .
