Chapter 2, Problem 2.19P

Consider a single-phase load with an applied voltage $v\left(t\right)=150\cos \left(\omega t+10°\right)\text{volts}$ and load current $i\left(t\right)=5\cos \left(\omega t+50°\right)\text{A}$. (a) Determine the power triangle. (b) Find the power factor and specify whether it is lagging or leading. (c) Calculate the reactive power supplied by capacitors in parallel with the load that correct the power factor to 0.9 lagging.
