Solution 1

The power P of an electrical device is given by the formula P = V^2/R, where V is the voltage and R is the resistance.

Step 1: Find the resistance of the bulb when it is operated at 220V and 100W. Rearrange the formula to R = V^2/P. Substituting the given values, we get R = (220^2)/100 = 484 ohms.
