Answer / mukhesh
power factor is cosine of angle b/w voltage and current
power is combination v&i
leads mens curnt leads voltate by 90d bcze cap means is
measure 2 dile plates in dieletric medium so leads in
inuctor dieletric medium is not tger so lags

Answer / 89
in capacitor current leads the voltage due to the usage of
dielectric medium in it but not for an inductor

Answer / umesh kumar
Power factor:- Power factor is the cosine angle difference
b/w voltage and current. current is always leading or
lagging if ur P.F is not unity, so to maintain the power
factor u have to check ur load circiuit.
Suppose if ur circuit have more Inductive load then it
will absorbs extra power and take the current lagging to
volatge.
And if we have connected Reactive power in the circuit then
it will generate extra power and it will take the current
leading to voltage.
if we have ballanced the circuit , balancing means if
inductive load is equal to capacitive load then the voltage
and current will be on the same phase and power factor will
be unity.

1)we have 1000 cfm Blower,Dia-1Mtr,Velocity of air 94 m/s 2)We have Natural Air velocity 94m/s 3If i Put Wind Mill in natural air ,speed is 94m/s Then it will generate Assume 100kw 4)If i put same wind mill across the Blower,air speed is same 94m/s now the Question is Will it generate 100 kw?
