Question 5

Essay

Given the following voltage and current on the load, find the power factor, average power, reactive power, complex power, and apparent power. Also, find the equivalent impedance, equivalent resistance, and equivalent inductance of the load. Draw the phasors for P, Q, and S.
The voltage and current are peak values. v(t)=140cos(2π60t+30)V,i(t)=12cos(2π60t+55)Av ( t ) = 140 \cos \left( 2 \pi 60 t + 30 ^ { \circ } \right) \mathrm { V } , i ( t ) = 12 \cos \left( 2 \pi 60 t + 55 ^ { \circ } \right) \mathrm { A }
