Answer / abid ali khattak

For the practically experiment of power factor we need to
connect the two type of same Wattage AC load with the
circuit. 1- inductive load. 2- Resistive load. and then we
need to be measured the current of both laod. We will find
that the inductive load getting more current then resistive
load.( lagging & Leading)
Beacause of inductance which induced in the inductive load.
which always oppose the provided EMF.

Answer / bhaskar

we need one wattmeter, voltmeter and amperemeter each.
observe the readings.
p.f. = Wattmeter reading/(volts*curr),ie. W/V*I

IN PRACTICAL POWER FACTOR IS DEPEND UPON LOAD
IF LOAD INCREASES MEANS RESULTS REDUCE IN P.F
