is directly proportional to power factor when current
increase p.f decrease so in order to improve capacitors is used

Answer / deepak

no effect

Answer / richa soni

if the voltage is increase p.f will increase because
we knowt8 p.f=v*i*cosA
v=p.f\i*cosA
therefor,if the voltage will increase p.f will also
increase and if voltage will decrease p.f will also
decrease.
