problem 3: 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.
In problem number 3, calculate the phase angle difference of the voltage
and current at t = 25 milliseconds. What is the real power and apparent
power at that time?
