Please enter your answer

i= sin wt f= 25 HZ w= 2×pi×f t=? 50=100 sin wt 50=100 sin (2×180×25) t 50/100= sin 9000 t 1/2=sin 9000 t Sin-' (1/2)= 9000t sin -' (1/2)=30 30= 9000 t t = 30/9000 t = 1/300 = 3.33 ms.

Solution: i = 100 sin(wt) 50=100 Sin(wt) wt = Arc Sin(1/2)= pi/6 radians but w = 2 pi 25hz= 50 pi wt = 50 pi t= pi/6 t= pi/6w= pi/( 6 x 50 pi) = 3.36 ms
