Question

Power rating of an appliance is 40 watt and 110 volt. Power rating of another appliance is 100 watt and 110 volt both the appliances are connected in series to a 110 volt supply. Calculate current flowing through each appliance.​

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.
