Determine the work of the electric current, if a charge of 75C has passed through a conductor under a voltage of 30V

From the condition, we know that the conductor is energized at 30 V, and we also know that at the same time a charge of 75 C passed through it.

Brief wash down the conditions of the problem:

U = 30 V (voltage under which the conductor is located);

q = 75 C (the amount of electricity that passed through the conductor).

To calculate the work of the current, apply the formula:

A = q * U (product of the amount of electricity and voltage)

All the data is there, substitute and calculate:

A = 75 Cl * 30 B = 2 250 J.

Answer: 2,250 Joules – work.
