Question

out of 60W and 40W lamps which is which one has a higher electrical resistance when in use ?​

Answer 1

Answer:

lamp powered 40W has more resistance than a 60W lamp.

Step-by-step explanation:

Power of lamp 1 = 60W

Power of lamp 2= 40W

Resistance and power are inversely proportional to each other

R =  V²/ P

R is inversely proportional P

So , lamp powered 40W has more resistance than a 60W lamp.
