In this video I will use another method to calculate (same problem as previous video) the capacitance of the shunt capacitor to change the power-factor=0.95 and final-phase-angle=18.195degrees given the V(RMS)=120V, f=60cycles/s, omega=377Hz, P=4000W, initial-power-factor=0.8, and initial-phase-angle=36.87degrees.
