The simplest method of power-factor improvement is by using appropriate capacitors, connected in parallel with the load. Power-factor improvement capacitors are rated in reactive volt amperes, not farads.

Do capacitor devices actually save power?
Your question should read, "Do capacitive devices actually save energy?" Power is simply the rate at which you use energy, so you cannot 'save' power. And the answer to your question is no.Capacitor banks are used to improve the power factor of industrial loads. Power-factor improvement acts to reduce the load current, thus reducing the amount of copper required in the supply system conductors, transformers, etc. Power-factor improvement, on the other hand, has no effect upon the operation of the load. The energy used by the load after power-factor improvement is exactly the same as it was before.Power-factor improvement only really applies to industrial loads, because utility companies will financially penalise industrial consumers who allow their power factor to fall below an agreed figure. Power-factor improvement will have absolutely no effect whatsoever on residential loads, so companies trying to sell you 'capacitor devices' that promise to 'save you money' are scam merchants!
What are the importance of capacitor?
It depends on the purpose where you are using the Capacitor.If you are using in power systems then it may be used for improvement of Power factor.Which is the important factor in industry.

Will the improvement of power factor will increase the efficiency?
Efficiency is defined as the ratio between the output power and the input power of a machine, expressed as a per unit or percentage. Power factor improvement has absolutely no effect on the behaviour of a load. All it does is to reduce the magnitude of the load current. A reduction in load current means that less copper can be used in the supply of energy to the load. However, it doesn't effect either the output or input power of the load. So the answer is no, power factor has no effect on the efficiency of a load. You could argue, however, that if improving the power factor of a load reduces the supply current, leading to lower line losses, then there is an improvement in the efficiency of the supply system.
Why capacitor is used in tube light circuit?
For power factor improvement so that the KVA demand is reduced.
What number is used as a factor in a power?
A base number is used as a factor in a power.
How can be determined the rating of capacitor bank?
If you are talking about a capacitor bank used for power-factor improvement, then it is rated in reactive volt amperes (var). Otherwise, it is rated in farads (F).
How can you improve your power factor in your Factory?
Improving the power factor of an industrial load acts to reduce the load current delivered by the electricity utility company, enabling them to reduce the amount of copper used in the supply lines, transformers, circuit breakers, etc. It also prevents the electricity utility company imposing a penalty charge applied to the factory's energy bill. The most common method of improving power factor under these circumstances, is by installing a capacitor bank at the supply's point of entry at the factory. It is also possible to install capacitors at individual inductive loads. Power factor improvement does not apply to residential loads, and any company offering 'power-factor improvement' capacitors for residential loads is a scam.
What does in a power the number used as a factor mean?
Numbers with exponents are sometimes referred to as a power. For example, x^4 can be called "x to the fourth power" which means that x is used as a factor four times. So, in a power, the number used as a factor is the base.
Why would a utility company insist on the correction of a low power factor?
If you are being billed on real power (in kilowatt hours) only, but have a very low power factor, that means the utility must oversize all equipment used to get power to you. A low power factor means you have significant reactive power in comparison to real power. Since total power (what equipment is sized to) is the vector sume of reactive power and real power, this results in more expensive equipment for the utitlity with no benefit (if you pay for real power only, and your rate is not based on power factor). Also, usually a poor power factor is due to inductive loads, which tend to drag the system voltage down. If you are on a long feed with weak voltages already, your (switching?) load may cause unacceptable voltage sag to other customers. If the utiltiy was implementing on their end, and you are the chief power factor offender, it may result in unwanted overvoltages to other customers when you are not online. The ideal place to correct such problems is at the load that is causing problems. This is so regardless of how you (or the other customers on the feeder) are billed.
What equipment is used in a nuclear power plant?

What is the harmonic factor in a power system?
Two factors reduce the power used by a piece of equipment compared to the volt-amps drawn from the supply: power factor and harmonic factor. Both factors increase the power transmission losses incurred in supplying a given amount of power.The power factor is less than 1 when voltage and current are out of phase with each other.When they are in phase the power equals the volt-amps except for a nonlinear load with a current that is not proportional to voltage. This generates harmonics in the current and the effect is that the power is less than the volt-amps, by an amount equal to the harmonic factor.
