The 'type' of power is determined by the load. If the load is resistive (e.g. a lamp) then the rate at which it consumes energy is termed 'true power', expressed in watts.
You seem to be under the impression that reactive power is 'pushed out' into a load. This is quite false; the loaddetermines the power.

What is the unit of measure for reactive power?
Volt Amps [volts times amps] is used for reactive and apparent power. Watts (dimensionally the same as volt amps) is used to indicate real power.AnswerReactive power is measured in reactive volt amperes (var).
Why reactive power is named as reactive?
Actually reactive power is a power which flows in between load to source which is a reactive action of the power given from source to load.the given power to load will not be utilised fully.some power will be oscillating from load to source.this is called reactive power.
What is the relationship of the reactive volt-amperes to the total volt-amperes in a unity-power factor circuit?
If you have unity power factor, p.f.=1, then the real power P must equal the total power S. Therefore, there is no reactive power being used, Q=0.Alternative AnswerApparent power is the phasor (vector) sum of true power and reactive power: (apparent power)2 = (true power)2 x (reactive power)2
What happens to reactive power in a circuit that has both inductance and capacitance?
Inductors are considered to be a load for reactive power, meaning that they will draw reactive power from the system. Capacitors are considered to be sourced of reactive power, they feed reactive power into the system. If you have a circuit that is at unity (balanced with inductors and capacitors) no reactive power will be drawn from the source. You will have unity power factor. If your circuit is more inductive than capacitive it will be drawing reactive power from the source. The opposite is also true for capacitors.
What are advantages of reactive power?
Real power is power that is used to do work. This is the power a light bulb uses to glow. Reactive power is power that is stored in one part of the AC voltage wave, and released in another. This causes the power to appear as a phase shift, and is generally caused by inductive or capactive loads. With regard to the power system, you can also get reactive power flowing due to unequal source voltages. Under these conditions, the apparent impedance of one source to the other will appear reactive/inductive, resulting in reactive power flow.
Is argon used in a light bulb?
yes argon is used for light bulb and it is not reactive
What is the electrical power of light bulbs what is it measued in?
Electrical power of a bulb is real power used by the bulb. It is measured in Watts. In general, the higher the bulb watt rating, the more lumens it will produce. This is not always the case, since some bulbs are more efficient than others at turning electrical energy into light (ie some bulbs produce more heat, an unwanted byproduct, than others). Real electrical power is always measured in watts. Total power (real and reactive) is measured in volt amperes, which is a vector summation of real power plus reactive power. Power times a time it is used is measured in Joules, or watt seconds.

How reactive power is used?
Reactive power (VARS) is required to maintain the voltage to deliver active power (watts) through transmission lines.Motor loads and other loads require reactive power to convert the flow of electrons into useful work.When there is not enough reactive power, the voltage sags down and it is not possible to push the power demanded by loads through the lines.

Does a light bulb emit carbons when used?
the electricity used to power the light bulb emit carbon dioxide
What is real power in electricity?
real power is to do do work and it is supplied to the load ,where as the reactive power is used for magnetising and the apparent power is the total power

Which line requires compensation?
Basically an AC transmission line require compensation in terms of reactive power. To push the active power across a transmission line certain amount of reactive power is necessary. In AC transmission line reactive power is generated and consumed. Generator is responsible for the production of reactive and active power both. Than this reactive power is consumed by the load and transmission line. Additional reactive power s supplied by the capacitor. This extra power supplied by the capacitor is termed as reactive power compensation. Requirement of this reactive power is there because reactive power is necessary to maintain the voltage stability.
Why wattmeter measure the reactive power?
A watt meter will measure active power, not reactive power.
