Answer / ullas k prabhu
Answer interms of the formula...
active power= V*I*cos(angle bw voltage and current)
reactive power= V*I*sin(angle bw voltage and current)

Answer / laxminarayana
The powe which is in phase with current is called active
power and which is perpendicular to the current is called
reactive power

Answer / denzel101
Reactive power is the power consumed by highly inductive
loads like induction motors (windings are highly inductive)
and supplied by capacitors
(power factor correction). in some cases this power can be
supplied into a power system by means of condensor motors
which can be made to run at leading or lagging power factor
depending on thier excitation.
Active power is mainly consumed by pure resistive loads
like a bulb or an electric kettle.
In a pure inductive load, the power factor is lagging
because the current wave lags behind the voltage wave by 90
degree.
In a pure capacitive load, the power factor is leading
because the current wave leads the voltage wave by 90
degrees.
A pure resistive loads has no phase shift. The current and
the voltage waves reaches maximum and minimum values at the
same time.

Answer / toshi
ans:Reactive power is defined as the swinging
power,swinging between the source and the load. it is
actually used for energising the reactive elements.
whereas, active power is defined as the consumable power or
it is the lost power.
it can also be defined as the power dissipated in the
ressitive circuits.

I want formula to calculate current loss with distance in km.I searched many sites but didn't right answer.Plz reply me
What happen if we apply square wave or traiangular waveform voltage to the transformer primary winding instead of sinusoidal wave?
What is meant by full pitched winding?

Alternator rotor earth fault relay circuit
Define stepper motor. What is the use of stepper motor?
1. Why is the speed of shunt motor practically constant? 2. Why dc series motor use to start with heavy loads? 3. advantages & disadvantages of separately excited generator over self excited generator?
why the all high voltage transformers are in 11kv , 33kv , 66kv, 132kv like that
hello everybody...i m an Elelctrical Engineering student.. i m in final year.. i m attending IOCL interview on 2nd aug. kindly let me know on wat subjects to concentrate more...any body who has attended the interview can help... others can also post their views... thankyou.
What is reactive power and where it is used.
