Assertion: Average value of `AC` over a complete cycle is always zero.
Reason: Average value of `AC` is always defined over half cycle.

Options

A. If both the assertion and reason are true and reason is a true explantion of the assertion.
B. If both the assertion and reason are true but the reason is not true the correct explantion of the assertion.
C. If the assertion is true but reason false
D. If both the assertion and reason are false.

Answer

B

Explanation

For half cycle `I_(mean)=0.636 I_(0)`
or `E_(mean)=0.636 E_(0)`
Average value is always defined over a half cycle cause in next half cycle it will be opposite in direction. Hence for one complete cycle, average value will be zero.
