A)60 sin 25 t
B)60 sin 50 t
C)84.84 sin 314 t
D)42.42 sin 314 t
B)60 sin 50 t
C)84.84 sin 314 t
D)42.42 sin 314 t
Answer. C)84.84 sin 314 t
Details calculation:-
I=Imax sin wt or I=Imax sin 2πft
where w= omega = Angular frequency (ω) = 2πf
Irms= 60A, Imax = 60(rms) x 1.414 , frequency (f) = 50 Hz
I= 60×1.414 sin 2x22/7 x 50t = 84.84 sin314t Ans
