What work does an electric current of 1.5A do in 5 minutes at a voltage of 36V?

Task data: I (current in a given circuit) = 1.5 A; t (duration of the current) = 5 min (in SI t = 300 s); U (voltage in the circuit) = 36 V.

The sought-after work of the electric current in a given circuit is calculated by the formula: A = U * I * t.

Let’s calculate: A = 36 * 1.5 * 300 = 16 200 J (16.2 kJ).

Answer: Electric current in 5 minutes will perform work equal to 16.2 kJ.
