Q33 neet_2024_05_may_morning Peak Value and Instantaneous Current
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?
  • A. (1)/(240) s
  • B. (1)/(30) s
  • C. (1)/(120) s
  • D. (1)/(60) s

Solution

Related Formula
i = ipeak (ω t) t = (T)/(4) = (1)/(4f)
Core Logic

Time to reach peak value from zero is one-fourth of the time period T.

t = (1)/(4 × 60) = (1)/(240) s
Pattern Recognition

Time to reach peak value from zero in AC is T/4.
