Assertion: AC generators are based upon ...

Assertion: `AC` generators are based upon `EMI` principle.
Reason: Resistance offered by capacito for alternating current is zero.

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.

Text Solution

Verified by Experts

The correct Answer is:
C

`X_(C)=1/(omegaC) omega ne0` area for `AC`.
`I_(rms)[(int_(0)^(T) I^(2) dt)/(int_(0)^(T)dt)]^(1//2)=[(int_(0)^(2pi//omega) I_(0)^(2)sin^(2) omegat dt)/(int_(0)^(2pi//omega) dt)]^(1//2)=(I_(0))/(sqrt(2))`.
