A certain current lags the voltage by 36 electrical degrees. The voltage waveform is increasing positively at t = 0 and an instantaneous value of 0 volt. If the frequency is 25 Hz, calculate at what time the current will be zero for the second time. What is the value of the voltage at that time? Peak values are 350 V and 50 A.
