The average value of A.C over a complete cycle is:
Correct answer: D. None of the above
- A. Io
- B. 1/2
- C. I
- D. None of the above
Explanation
The correct option, "None of the above," indicates that none of the provided options accurately represents the average value of an alternating current (AC) over a complete cycle. In reality, the average value of AC over a complete cycle is zero because the positive and negative values cancel each other out.

About Alternating Current
Alternating current varies periodically, so phase relationships become essential when current passes through a resistor, capacitor or inductor. The chapter distinguishes resistance from capacitive and inductive reactance, explains phase lead and lag, and connects changing electric and magnetic fields with the production and properties of electromagnetic waves.
