Answer / rohit

1> when reactive power increases, real power decreases so as the power factor.

2.a> in case of a linear load, only the phase difference between the voltage phase & current phase increases.
2.b> in case of non-linear loads, the shape is distorted giving rise to unpredictable feedback to the generating station in terms of current & uncontrolled power factor due to the high returning current.
For which power factor rectification is used, generally passive networks containing only inductive or only capacitive elements.

Answer / m.omar javaid

Reactive power is not useful,it affects the excitation and
magnetic fiels of machines.When reactive power increases
then definitely reactive power loss increases i.e I^2*X.
