Verified by Experts


See Fig. In this case, the frequency of the alternating current (AC) produced is 50 Hz. The coil completes 50 rotations every second. The time for second, It is called the one rotation of the coil is periodic time or simply the period of AC. Positive current means the current flows in one direction and negative current means the current flows In the opposite direction in the external circuit. Here the maximum value of AC is 5 A.
