Power factor is a measure of how far out of alignment current wave is from the voltage wave form, Ideal power factor is 1 to 1 or as with most meters simply 1. Ie both wave forms are insynch thus power used is accurate to power consumed.
As power factor starts to lead or lag it appears to the watt meter that more power is being used then is actually being consumed by the device. This means a larger bill for power that you didn't actually consume.
Highly inductive or capacitive loads cause power factor to go out of synch, if you are running a capacitive load you can realign power factor by adding an inductor or vice versa.
Use a voltmeter to measure the supply voltage and an ammeter to measure the load current, and use the product of these to determine the apparent power of the load in volt amperes. Use a wattmeter to find the true power of the load in watts. Divide the true power by the apparent power to give you the power factor.
Power factor is the ratio of apparent power divided by true power. In a sinusoidal configuration, it is the cosine of the phase angle between voltage and current.
THE power factor is can be maintain with incandescent lamp and capacitors synchronous motors
by using capacitor & inductor

A wattmeter reads the true power of a load, regardless of its power factor.
Power factor is defined as the ratio of real power over total power. Total power is the vector sum of real and reactive power.
The power factor depends on the properties of the load, and if any power factor correction is done it has to happen at the load, so that the current in the transmission lines is reduced. Correcting the power factor at the sending end fails to address the problem.
A resistor doesn't have a power factor. However, if a circuit is pure resistance in nature the power factor will be one when a voltage is applied and a current flows in the circuit. The power factor is a measure of the relative phases of the current and voltage in a circuit.

Calculate the sums on the board.We calculate that the temperature will rise.
power factor means kw/kva
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.
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.
There is no significance to a power factor of 0.82.

There is no such thing as a 'low power-factor' wattmeter. A wattmeter always reads true power, regardless of the load's power factor.
