The load on a 120 V, 60 Hz supply is 5 kW (resistive), 8 kVAR (inductive), and 2 kVAR (capacitive).

a. Find the total kilovolt-amperes.


b. Determine the Fp of the combined loads.


c. Find the current drawn from the supply.


d. Calculate the capacitance necessary to establish a unity power factor.


e. Find the current drawn from the supply at unity power factor, and compare it to the uncompensated level.
