Question

there are two electric bulbs marked 60W,220V and 2nd marked 100W, 220V which one of the two has a higher resistance

Answer 1

Formula for calculating Power P is P=V*I or P=V^2/R

As we can see that V is same for both the bulbs. So, by considering the above formula P is inversely proportional to R(Resistance). So, bulb giving power of 60 watt will hae higher resistance.
