In electrical or electronic circuits, impedance can be said to have capacitive or inductive components. Capacitors cause capacitive impedance, and coils (chokes, Transformers, loudspeakers, etc.) cause inductive impedance.
A capacitor is said to be a reactive component in an AC circuit because it holds charge, then releases it, causing a phase shift in the output current. This phase shift in current equates to a phase shift between current and voltage. Reactive power is defined as a phase shift between current and voltage.

What is VAR?
Volt-Ampere Reactive. It is the reactive component of power when the Power Factor is less than unity (1.0). It is usually measured in KVAR - 1000's of VAR.
When is an element said to be chemically reactive?
An element is said to be chemically reactive when it combines with another element. These two elements will create a new compound.
When the outer energy level of an atom is full the element is said to be non reactive or inert is called?
If the outer energy level is full, the element is said to be non reactive and inert. It is stable in nature.
How do you decide KVAR rating of capacitor bank?
Generally the capacitor rating of a bank are decided on the load factor.ie higher the KVAR higher the capacity.KVAR is the reactive power in which load angle differs with the load variation.If we know load factor multiply it by the sine angle which gives us the capacity of the cpapcity of the load bank.

How can soda ash remove reactive silica in water?
Reactive silica solubility in water depends on the pH and increases as pH increases from 7 onwards. Soda ash has a component of CO2 Which forms carbonic acid decreasing pH. Hence the lower pH precipitates reactive sliica.
Why power rating of capacitor is reactive in nature?
A capacitor is composed of metal plates. Voltage is applied to one, which causes electrons to build up on the other. This is reactive in nature, thus a capacitor is reactive. It stores a charge, and releases this charge when the voltage decreases.
What electrical component can hold a charge?
A capacitor
How can you reduce reactive power?
If, for example, the reactive power of a load is due to its inductance, then installing a capacitor in parallel with the load will reduce the overall reactive power.
What is the simplest component in a filter circuit called?
capacitor
Component that acts like a little battery?
Capacitor
What electronic component can temporarily store electricity?
A capacitor.
How can improve the power factor?
To increase capacitive load and decrease inductive loadAnswerThe most common method is to add a capacitor, or a capacitor bank, in parallel with the load. In practise, the reactive power of the capacitor (they are not rated in farads, but in reactive volt amperes) must be a little short of being equal to the reactive power of the load, so that the power factor approaches, but does not equal, unity.
What is VAR?
Volt-Ampere Reactive. It is the reactive component of power when the Power Factor is less than unity (1.0). It is usually measured in KVAR - 1000's of VAR.
In the circuit shown if the value of the reactive component was increased?
if the value of the reactive component was increased, how would it change the waveforms?
Why there is no reactive power in DC system?
In case of dc there is no reactive components and current drawn from the supply is in phase with the voltage.due to absence of inductor and capacitor the reactive power demand in dc is zero.
What method improve power factor?
The most common method of improving the power factor of a load is to connected a capacitor or capacitor bank, of appropriate reactive power (expressed in reactive volt amperes), in parallel with the load.
Which electronic component can store a charge?
A parallel plate capacitor is an electrical component which can store charge. The charge is stored according to the equation: qo = q(1-e-t/RC) [in a charginr circuit.]
