hello again
a sinusoidal current is specified by the expression, i=0.1 sin (200 pie t +pie/2)
determine a.) the peak value of the current, b.) the frequency of the current, c.) the phase angel, and , d.) the instantaneous value of the current at t=5 milliseconds (use radian measure)
for a i have
i=0.1 sin(200 pie t + pie/2)
i=0.1 sin(200 pie 0.005 + pie/2)
i= 0.1 sin (3.142 +1.57)
i=0.082 peak to peak
ipeak=0.082/2
ipeak=0.041A
b.) f= 1/t
f=1/0.005
f=200 Hz
could you tell me if i am correct thus far
for c.) i have found the equation sin(t+pie/2)=cos(t)
is that correct one to use, if so how do i impliment it?
for d.) not sure what to do there - any help would be greatly appreciated
cheers guys
