power factore is The Ratio Of Loss Of Inductive Load
Between true Power And Aperant Power Also It Can Define In
Cosin Angle Between Voltage And Current.

Answer / sanjay

Power factor is cosin angle between voltage and current.

Answer / bindu

It is the ratio between active power and reactive power.

Answer / shashidhara tm

It is an indication of what fraction of the sending end VA
is actually converted in to energy Like heat, torque,
etc......... either useful or otherwise... It is
numerically equal to the ratio of Active Power-P to
Apparent Power-S.
Incidentally, this quantity in Sine waves is equal to R/Z..
or Coa(angle between v and I)....
But in circuits with non-sinusoidal waveforms of v & i, it
is to be found by P/S...

Answer / sagar

power facor means ratio of true power(kw) and apperant(kva)
power.

Answer / simon

P.f=Real Power/Apperent Power OR V.I.CosPie OR Resistance/Impedance OR R/Z.

Answer / thamizh

IT CAN BE DEFINED AS THE RATION BETWEEN RESISTANCE AND IMPEDANCE

COS0=R/Z

In a power conditoining unit (inverter) of a solar plant when we measure the d.c. current fed by different strings of solar plates to inverter, the current in the negative wire is less almost by 1 ampere to the current in its positive wire say current in positive wire 5 A , then current in negative wire of the same string is 4 A. Since the current entering should be equal to current leaving then why the current is noticably less in negative wire.
