The current from an AC source is given by: I(t) = 10.10 sin(70.0 t + 0.830 ) mA, where t is given in seconds.
(a) What is the RMS current IRMS?
(b) What is the frequency f?
(c) If the phase shift were given in degrees, what would its value be?
(d) What is the time t0 closest to t = 0 when the current vanishes?
