Figure 2.6 depicts this circuit as a voltage source applied to a
resistor and inductor in parallel (disregard the capacitor for part
A), which is to be an equivalent to the load. Why is a
resistor and inductor in parallel used for the load versus just
using a resistor?
Find the following (show calculations):
Real power absorbed by the load.
Apparent power of the load.
Reactive power of the load. Don’t use the tangent
function. Instead, find the reactive power using the
apparent...
