Calculate the electricity consumption of an electric iron connected to a 220V network for 20

Calculate the electricity consumption of an electric iron connected to a 220V network for 20 minutes, if the force in the circuit is 5A?

Task data: t (duration of operation of the electric iron) = 20 min (in SI t = 1200 s); U (mains voltage) = 220 V; I (current in the circuit) = 5 A.

The electricity consumption of an electric iron taken can be calculated using the formula: W = P * t = U * I * t.

Let’s calculate: W = 220 * 5 * 1200 = 1,320,000 J (1.32 MJ or 366.7 W * h).

Answer: The electricity consumption of the taken electric iron is 1.32 MJ or 366.7 W * h.
