Question

a bulb draws 1A current when it is connected to a supply 220 V . what current will it draw if the voltage drops to 55V​

Answer 1

Answer:

The power dissipated by an electric bulb is given as P = VI.

In this case, Power P = 100 W and Voltage V = 220 V.

So, current I is I = P/V = 100/220 = 0.45 A.

When the supplied voltage is 110 V, the power consumed will be P=VI = 110 * 0.45 = 50 W.

Hence, the power consumed when operated at 110 V is 50 W.

Answer 2

Answer:

apply the formula of current
