Answer / shiv

Due to inductance of the winding coils. Inducitve load
absorb reactive power because it utilises this power for
the magnatising current.

Answer / ujjwol

Reactive power is produced by the synchronous generator basically due to the excitation current supplied to it. The VAR it can produce can be controlled by controlling the excitation current with the help of AVR.

The unit of current is the:(a) Volt(b) Coulomb(c) Joule(d) Ampere

why we step down voltage level from 33kv to 11kv and 11kv to 415v.Instead we can step down voltage from 33kv to 415v directly using single transformer.
