Answer / kavitha.s

it is ratio of active power to apparent power is called
power factor. it is expressed as PF= KW/KVA

Answer / bhupendra

Power factor is cosine of angle b/w voltage & current.
Mathematically
Cosφ=Power/Voltage*Current)
Cosφ=R/Z
where R= Resistance
Z= Impedance

Answer / shaikh aijaz

it is the cosine angle between voltage and current,
and from impedance trangle it is the ratio between
rasistance and impedance,
cos0=r/z
it is also define as the ratio between active power and
apparent power.cos0=kw/kva

Answer / amit rajak

power factor is the cosine angle between voltage and current
which balances both these electrical quantities.It is
ideally considered as 0.8 for electrical equipments for its
maximum efficiency.if it is not properly regulated than
there may be rise of any one of the above parameters which
will definitely effect the efficiency


it can be properly regulated by using capacitors in
domestic installation systems
