Electrical inductive motors, Transformers and magnetic ballasts bring real power that are measured in kilowats and reactive power (measured in kilovolt-amperes reactive, kvar). Real power genrates "productive" work. Reactive power does the the magnetic field required for inductive devices to operate.
A poor power factor causes the meter to rotate more slowly than it should, so a poor power factor would reduce your bill. Electric utilities compensate for this in commercial services by billing based on power factor, or they install a meter that actually measures power factor.AnswerEnergy meters 'read' the in-phase component of load current (therefore the load's 'true power' multiplied by time) and, so, are completely unaffected by the power factor of a load. So the power factor of a residential load will have absolutely no effect whatsoever on that residence's 'energy' (not 'power') bill.Industrial and commercial consumers are billed for 'demand' (their rate of consumption of energy -i.e. the power) as well as energy supplied'. In addition, these consumers are usually penalised if the power factor of their load falls below an agreed value. So power factor does affect the overall bill (but not the energy bill) of industrial consumers.
Output Power divided by Power Factor.
There is no disadvantage of unity power factor, because at unity power factor all the electrical power is efficiently utilized by the the load, and at lagging power factor some power is lost in the load's magneticfield.
Power-factor correction doesn't save energy. Power-factor correction is used to reduce that magnitude of the current drawn from the supply in order to minimise the cross-sectional area of the supply conductors and associated equipment -thus keeping down the cost of the supply circuits which are owned by the supply company. Power-factor correction doesn't apply to homes, but only to larger commercial or industrial premises. The electricity supply company will negotiate a value of power factor for the load, and apply a penalty charge to the customer if his load is not kept within that agreed value.
There is no such thing as a 'low power-factor' wattmeter. A wattmeter always reads true power, regardless of the load's power factor.

It varies based on the ballast. Most ballasts nowadays are "power factor corrected" to try and compensate for the bad powerfactor in switching power supplies. The actual power factor of a individual fixture is entirely dependent on the circuit of the ballast, which changes from design to design.
To decrease virtual power and hence increase efficiencyAnswerThere is no such thing as 'virtual power', and power factor has nothing whatsoever to do with 'efficiency'!Power-factor correction, or power-factor improvement, only applies to large commercial or industrial loads. It does not apply to residential loads.Power factor correction acts to reduce the supply current to resistive-reactive loads. It has no effect on the load itself, does not reduce its energy consumption, or its efficiency.By reducing the supply current, the utility company can install cables with lower cross-sectional area, and reduce the amount of copper in its supply equipment -thus reducing its costs. To encourage companies to improve their power factor, electricity tariffs include penalties for low power-factor loads.
power factor means kw/kva

When looking at power factor, it is the ratio of watts (true power) to VA. The power factor is how we measure power systems. A person with a low power factor like .26 will have a higher electricity bill.
For residential load, power-factor improvement is irrelevant as it will make no difference to the quantity of energy consumed and, therefore, the electricity bill. For industrial/commercial consumers, poor power factor results in additional charges over and above those for the amount of energy consumed. The electricity supplier will specify a value below which these additional charges will be imposed, so it's in the interests of the consumer to ensure the power factor of their loads doesn't fall below that agreed value.

You get x factor tickets by calling the number in the commercial.
There is no significance to a power factor of 0.82.
