Power Factor is a maximum of one when the voltage and current in an AC waveform are in phase. Since power in watts is equal to voltage x current x power factor, you get maximum wattage with power factor = 1. This occurs with a pure resistive load. When you power an inductive load like a motor the power factor decreases and so does the delivered power. That is why motors are typically rated in VA, or volt-amperes rather than watts. So y Ou can assume power factor = 1 when you have a load measured in watts like a light bulb or space heater and perhaps in the .75 range for an inefficient motor.
What else can I help you with?
How do you find power input with given power factor and power output?
Output Power divided by Power Factor.
What are the advantages and disadvantages of unity 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.
Why you use low power factor wattmeter on primary and unity power factor on secondary side of transformer?
There is no such thing as a 'low power-factor' wattmeter. A wattmeter always reads true power, regardless of the load's power factor.
What is simultaneity factor in power distribution?
Not all the loads in an electrical installation operate at their nominal power all the time. A good example are the plug sockets which are rarely used at their maximum output (which in this case would be the limit of the protective fuse of 10 or 16 amps). So, in order to get a realistic image of the power demand, there is also a simultaneity factor applied. But each tipe of consumer can have its own factor depending on the tipe of load, ratio of its usage and also on the interpretation of the engineer. Coming back to the example with sockets, usually a coefficient of 0.2 is taken into consideration but for other loads that are operating at their nominal current/power(like lighting) a higher factor up until 1 would be assumed. By multiplying the nominal power with simultaneity factor you will get the power demand.
What is PFI panel?
Power Factor Improvement Panel. It controls power factor
What is the formula to calculate ac current in single phase 240volts?
The formula is: current (in amps) = power (in watts) , divided by (240 times the power factor). The power factor is 1 for incandescent light or heaters, otherwise it can be assumed to be 0.75 for other loads.
After emporor meiji died who assumed the power?

Who assumed the power after emporer Komei died?
Emperor Kōmei was emperor of Japan from 1846 through 1867. Emperor Meiji assumed power after he died.
How do you spell awsempchen?
The likely word is assumption (something assumed, or an expected factor).

What mean power factor 0.26 lead?
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.
When did manufacturing become important to Slovakia?
After the Communist assumed power.

There is no significance to a power factor of 0.82.
