Answer / k.prakashchandra

Active power increases with the load.

Answer / sharan dilip

In the -ph systems the pf decreases as load Increases.
But In the induction motor it quite different.
At no load or light load the current drawn by induction
motor is is comparable with the magnitude of the magnetizing
current which lags much behind the applied voltage and hence
low pf @ low or no-loads.
While the load increases the current drawn by the induction
motor increases. As the secondary of i.m. is short
circuited.The current operates at a higher power factor.

Answer / sandeep

cos pi=active power(kw)/apparent power(kva)
if load increases current increases then kva increases
