Question { 18776 }

why the power factor in inductive load is lagging while it
is leading in capacitive load?

Answer

as power factor is a cos angle between voltage ¤t.In
inductive load current lags,means the voltangle between age
and current goes upto 0 to 90 degree(we assume voltage is
constant).in capacitive load current leds, it means angle
between voltage and current comes down from 90 to 0
degree.And we know cos 90=0,and cos0=1.
