The instantaneous value of current in an a.c. circuit at any time t seconds is given by:
i = 50 sin(100t - 0.45) mA. Determine
(a) the peak to peak current, the frequency, the periodic time and the phase angle (in degrees and minutes) (b) the current when t = 0 (c) the current when t = 8 ms (d) the first time when the voltage is a maximum.
Sketch the current for one cycle showing relevant points.
