In alternating current the average value of current in cycle is
Correct answer: D. max:
- A. 0
- B. Constant
- C. +
- D. max:
Explanation
The average value of current in an AC cycle is equal to the maximum current (amplitude) divided by the square root of 2.In summary, option (d) "max" is the correct statement for the average value of current in an alternating current cycle.

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.
