Answer / abbas haruna

is the phase angle between the voltage and the current in
alternating current circuit

Answer / devesh mishra

p.f can be defined as:
a)Cosine of phase angle b/w V & I.
b)effiency of any machine.
c)current consumption of any machine as P=VIcos @
i.e cos@=P/(VI)=p.f
I=1/p.f
i.e more the p.f ,lesser the current consumption .

d)the rate of tariff charged by the electricity
boards.
