What work does a constant electric current do in the electric circuit of a car fan in 30 s

What work does a constant electric current do in the electric circuit of a car fan in 30 s, if at a voltage of 12 V, the current in the circuit is 0.5 A?

These tasks: t (the duration of the car fan) = 30 s; U (voltage in the circuit) = 12 V; I (current) = 0.5 A.

The work done by a constant electric current in 30 seconds of operation of the car fan is calculated by the formula: A = U * I * t.

Let’s calculate: A = 12 * 0.5 * 30 = 180 J.

Answer: For 30 s of operation of the car fan, a direct electric current performed work of 180 J.
