Derivation of ac average value for half cycle in tamil

Amplitude:
It is the highest value attained by the current or voltages in a half cycle either positive or negative half cycle of an alternating quantity.
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.
Thank You for watching

I forgot all basics..after 5 years i recall all..thanks for your info sir..you are like my staff

[@பாரதகவிதெட்சிணா]

Thank you for this class Sir. I had so many doubt for this question. Finally i have cleared from this class.

[@jananiselvakumar1322]

Superb sir...

Sir not mention given circuit behaviour like full wave rectifier. Half wave rectifier--->avg.Volt=(max.voltage/π) Full wave rectifier----> Avg.Volt=(2*max. voltage/π)

[@primedecay13]

What is Vm sir??

[@Nareshdurga777]

Maximum voltage
