Question
An electric bulb is rated 100 W and 220 V. What is the
current through the bulb? ÂSolution
Power P = VI ⟹ I = P/V = 100 / 220 = 0.45 A This tells us how many current flows in the bulb at 220 volts.  It helps prevent overloading in circuits.  Appliances are designed with such ratings for safety.
