1. A sinusoidal alternating voltage has an RMS value of 440 V and a frequency of 50 hz. It crosses the zero axis in a positive direction when t-0. Determine a) the time before passing through its negative maximum reaches the value of 225 V, b) the time to reach a value of 300 V before coming to a period.
