At a voltage of 220 V, the current in the motor of the fan heater is 0.1 A. What work does the electric current do in the electric motor in 30 s?

The amount of heat released in the circuit is Q = UI * t. Where U is voltage, I is current. Then we substitute our values into the equation:
Q = 22 * 30 = 660J
