What is the average current?

What is the average of the square of the current?

What is the amplitude of the current?

Searched high and low!!! Cant find the right formula

The average current is 0 (it is AC).

The average of the square of the current is 2.7 * 2.7 = 7.29 Amps squared. (RMS means Root Mean Square)

The amplitude of the current is 2.7A RMS.
