[ Prob. 3] The voltage is = 20 sin ( 377t + 15 ) volts and the current is = 4 sin ( 377t - 15 ) amperes. Determine the following: frequency, real power, reactive power, apparent power, power factor...

Please show your solution clearly thank you

Extracted text: [ Prob. 3] The voltage is = 20 sin ( 377t + 15 ) volts and the current is = 4 sin ( 377t - 15 ) amperes. Determine the following: frequency, real power, reactive power, apparent power, power factor Then in a graph, sketch 1/4 of the waveforms both from min. to max. Specify the ff: phase of v & i; amplitude level/value of v & i; location of max values in degrees, phase angle difference between voltage and current.
