Answer Posted / jai prakash narain singh
REACTIVE POWER-This is called useless wattage,means
losses,reactive power=root of 3Xvoltagexcurrentxsine angle
between volt and current.this is reactive power and unit is
KVAr.when power factor is unity ,KVARwill be zero.that
means apparent power is equal to true power or real power
kva(apparent power)=true power(kw)
active power and real power is same,that is called true
power also.
active power=root of 3 xvoltage x current x power
factor.this will depend on types of load.
active power and real power ,both are same
