Three parallel impedances in rectangular form as follows:
8.66+j5 ohm , 25+j0 ohm , 3.54+j2.54.
A 240 volt 50 Hz supply
Calculate overall power factor of the three loads.
Convert each impedance to admittance
Z1 = 8.66+j5
Y1 = 1/Z1 = ...
This solution shows step-by-step calculations to determine the overall power factor of the three loads by first converting the impedance to admittance and then finding the total admittance.
