Recall the CFL nonlinear loads measured in Lab 3. The current drawn by a CFL has a high

total harmonic distortion, 45%. Assuming the voltage source is stiff.

a. Calculate the distortion power factor.

VRMS and IRMS are measured to be 118 V and 89 mA, respectively. The CFLs draw 9.2 W.

b. Calculate the true power factor.

c. Calculate the displacement power factor.
