3. A sinusoidal alternating voltage has an r.m.s. value of 200 V and a frequency of 50 Hz. It crosses the zero axis in a positive direction when t= 0. Determine (i) the time when volt- age first reaches the instantaneous value of 200 V and (ii) the time when voltage after passing through its maximum positive value reaches the value of 141.4 V.
