| **Determine the work of the electric current at a current of 5.5A, if the consumer resistance is 1200 Ohm. And he worked for 30 seconds. Calculate its power consumption.**

The work of the current is directly proportional to the square of the current strength, resistance and time:

A = I ^ 2 * R * t = 1089kJ

And the power P is directly proportional to the square of the current and resistance:

P = I ^ 2 * R = 36.3kW
