aktually power factor is the ratio of apparant power and
aktual power flow in the cirkuit.
i.e. cos # = kva/kw
in kommon wrds.. power factor is the amount of power
konsumed in the unit power supplied.
always power factor should be high.
as high as the power factor, the efficiency vl b high

Answer / dj
Power factor is define as degree to which a load is matches with the pure resistive load.
COS#= Real Power(watt)/Apparent Power(VA)
Apparent power (VI) is the power when we assumed that load is pure resistive
While Real power is that power our actual load receive.
We just comparing our load true load with pure resistive load.
i.e when unity means our load is equal to resistive load.
