An electric fan runs from the 230V mains. The current flowing through it is 0.4A. At what rate is electrical energy transferred by the fan?

Electric fan works on the principle of

In an electric fan, electrical energy changes into mechanical energy. True/False.

An electric heater is connected to the 230V mains supply. A current of 8A flows through the heater. (a) How much charge flows around the circuit each second? (b) How much energy is transferred to the heater each second?

An electric fan has an electric motor inside to-change

A particle on a blade of the electrical fan moves in

Why does the electric fan continue to rotate for some time after the current is switched off ?

Five electric fans of 120 watts each are used for 4 hours. Calculate the electrical energy consumed in kilowatt-hours.
