EE 212 Lab Prelab 5: Power Factor Compensation

1. For the circuit shown in figure 1 of the lab, determine the following:
   • load impedance Z_L
   • load power factor angle
   • load power factor
   • complex power absorbed by the load
   • expected time shift between load voltage and current
2. Determine the value of a capacitor C that when placed in parallel with the original load impedance (see figure 2) yields an equivalent power factor of 1. What is the value of this equivalent impedance? What do we expect for the load voltage and current, and their relationship to the source voltage.
