The peak value of alternating current is 5√2 A. The mean square value of current will be:
Correct answer: A. 5A
- A. 5A
- B. 2.5A
- C. 5√2 A
- D. 52 A
Explanation
The mean square value (RMS value) of the current is calculated as:RMS value = Peak value / √2= 5√2 / √2= 5 A Therefore, option a is correct.

About Phase of Alternating Current
Phase describes the position of an alternating voltage or current within its cycle and the phase difference between two sinusoidal quantities. The topic covers in phase signals, phase angle and lead or lag in resistive, inductive and capacitive circuits, rather than the amplitude or frequency of the supply.
