The ohm's say's V is directly prop to I it means if v raises its value the value of I. will raise automatically. The formula of P.f=v*i*cos fie. Hense if the value of V is increased then the value I will increase .Motor will draw less current , v from the supply & it will b known as good power factor of motor .
