his Course SU Community Moodie community. Moodie com 6 a Fig. 2 shows a generator connected to an electric cicuit (efered to as Black Box that could possibly contain a combination of resistance, capacitance and inductance. Blackbox\' simply means that the contents of the cirouit is unknown. You wilnow determine some information about what is in the black based on your knowledge of R-L cciouts. The generator supplies an alternating emt E(y-65.8 v sin tw and eheresulting currentis iro-2somA sin Wat-1501. What is the power factor of the circuit? Give your answer in the form \'abc. 6 b Does the current lead or lag the voltage? Give your answer in the form \"lead\' or \'lag 6.c What is rms value of the voltage? Give your answer in the form \'abc

Solution

6a) cos 15°=0.965

6b) current lag by 15°

6c) RMS value= peak value/2=48.51

6d) no

6e) a resistor and inductor

6f) power=(48.51*17.68*0.965)=827.65mw
