AC Fundamentals – 61

5555555555

61. A sinusoidal current has an rms value of 14 mA. The peak-to-peak value is ________.

(a) 45.12 mA
(b) 16 mA
(c) 39.6 mA
(d) 22.6 mA

Answer
Answer : (c)
Explanation
Explanation :

Ipeak = √2 * Irms = 1.414 * Irms

Since it is a sine wave, +14 and -14.  Hence, Irms = 28 mA.

Ipeak = 28 * 1.414 = 39.59 mA = 39.6 mA.
