What work does the electric current perform in the circuit in half a minute if at a voltage of 12000 mV the current is 5 * 10 ^ 7 μA?

The work of an electric current can be calculated using the formula:
A = I * U * t, where I is the strength of the electric current in the circuit (I = 5 * 10 ^ 7 μA = 50 A), U is the voltage in the network (U = 12000 mV = 12 V), t is the operating time of the electric current (t = 30 s).
Let’s calculate the work of the electric current:
A = I * U * t = 50 * 12 * 30 = 18000 J = 18 kJ.
Answer: The work of the electric current is 18 kJ.
