A sinusoidally alternating current of frequency 60 Hz has a maximum value of 15 A. Find the value of current after 1/200 second |
|
Answer» Given maximum current Imax = 15 A frequency of alternating current = 60 Hz t = 1/200 sec We know that I = Imax sin 2π ft I = 15 sin 2π x 60 x t I = 15 sin 120π x 1/200 I = 15 sin 3π/5 I = 15 x 0.95 I = 14.25 A |
