Directions : In the following questions, A statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as.
Assertion: Average value of ac over a complete cycle is always zero.
Reason: Average value of ac is always defined over half cycle.
  • a)
    If both assertion and reason are true and the reason is the correct explanation of the assertion.
  • b)
    If both assertion and reason are true but reason is not the correct explanation of the assertion.
  • c)
    If assertion is true but reason is false.
  • d)
    If the assertion and reason both are false.
Correct answer is option 'B'. Can you explain this answer?

Directions : In the following questions, A statement of Assertion (A)...
The mean average value of alternating current (or emf) during a half, cycle is given by Im = 0.636 I0 (or Em = 0.636 E0) During the next half cycle, the mean value of ac will be equal in magnitude but opposite in direction. For this reason the average value of ac over a complete cycle is always zero. So the average value is always defined over a half cycle of ac.

Directions : In the following questions, A statement of Assertion (A)...
Explanation:

Assertion:
- The average value of ac over a complete cycle is always zero. This is true because in an alternating current (ac) circuit, the current changes direction periodically, resulting in positive and negative values balancing out over a full cycle.

Reason:
- The average value of ac is always defined over a half cycle. This is also true because the average value of ac is calculated over a half cycle to account for the changing direction of the current.

Explanation:
- Both the assertion and reason are true in this case. The average value of ac over a complete cycle is indeed zero, and the average value is typically calculated over a half cycle to simplify the calculation. However, the reason provided does not directly explain why the average value over a complete cycle is zero. Therefore, option B is the correct choice, as both the assertion and reason are true, but the reason is not the correct explanation of the assertion.
