The maximum value of a voltage is 25 volts and it is attained in 24 milliseconds in case of an inductor. At what time does current reach its maximum value?
Answer & explanation
Correct answer: option 4
Phase difference between current and voltage is 90º or one fourth of time perod.
Current reaches its maximum value later than the voltage by one-fourth of a period.
1/4(24 msec) = 6 msec
The current reaches the maximum value at : T = 24 msec + 6 msec = 30 msec
