AC Basics: Peak, RMS & Average Values

The peak value of an alternating current is 5 A and frequency is 60 Hz. How long will the current, starting from zero, take to reach the peak value?

Show answer and solution

Answer: (d)

  1. From zero to peak takes a quarter cycle: t=T4=14ft = \frac{T}{4} = \frac{1}{4f}.
  2. t=14×60=1240t = \frac{1}{4 \times 60} = \frac{1}{240} s
  3. So the answer is (d) 1240\frac{1}{240} s.
