An electric bulb of

Answer :

In this case we have been given power P and voltage V, so the formula to be used for calculating the current will be: P = V × I Here, Power, P = 40 watts Voltage, V = 220 volts And, Current, I =? (To be calculated) Now, putting these values in the above formula, we get: 40 = 220 × I I = = Thus, Current, I = 0.18 amperes.
