AC average value for half cycle only in tamil

How to calculate the ac average value of one cycle.

Cycle:
One complete set of positive and negative value of an alternating quantity is called a cycle.

Time period (T):
The time required for a sine wave to complete one full cycle is called Time period.

T = 1/F sec (or) m sec.
F = Frequency.

The period of a sine wave can be measured from a zero crossing to the next corresponding zero crossing.

The period can be also being measured from any peak in a given cycle to the corresponding peak in next cycle.

Peak value or Maximum value:
The peak value of a sine wave is the value of voltage (or current) at the positive or the negative maximum with respect to zero.

Average value or Mean value:
This is the average of the instantaneous values of an alternating quantity over one complete cycle of the a.c waveform.
It is also known as Mean value.
