Question

The equation of alternating current is i = 42.4sin(628t). Then the average value of current is
Options
A 2A
B 38A
C 27A
Correct Answer
D 42.4A
Correct Answer

Option C is the correct answer.

Detailed Explanation

The average value of a sinusoidal current over a half-cycle is I_avg = 0.637×I_max = 0.637×42.4 ≈ 27A.

Hint

Use I_avg = (2/π)×I_max for a sinusoidal waveform.
