That's the ratio between true power, and apparent power. It applies to AC. Apparent power is voltage x current, and in the case of DC, this is also the true power. In the case of AC, it is possible that voltage and current are not in phase; in the extreme case that they are 90 degrees out of phase, they true power is zero (instantaneous power will be positive for part of the cycle, and negative for another part of the cycle).

how to calculate the powerfactor in capacitor
What the reason of getting minus power factor reading?
its nothing but a lagging powerfactor...its due to inductive loads......
Give some technical word for electrical department?
armature , electrostatic , electromaganetic , commutator,dampe winding,dashpart,voltage ,powerfactor etc..
Design of a auto switching capacitor bank power factor improvement plant?
the powerfactor actuator are available in market. Use them with ADC to switch required capacitors. I hope you can work out with this
What is the most commonly used value for power factor during design works?
It depends on the application the desgn is for, but 0.8 is the most commonly used powerfactor for general design especially home use.
What areVolt ohm ampere and watts associated with?
Volts = current (In amps) x Resistance (In ohms) Watts = Volts x Current x PowerFactor Power Factor = 1 in a pure resistive circuit
At what power factor do commercial 4 tube fluorescent fittings usually operate or can they vary?
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.
How do you work out ampere hour?
An ampere-hour is one ampere for one hour.A ampere is one coulomb per second, so an ampere-hour is a transfer of charge of 3600 coulombs.See the discussion page.
Is current reduces with increase in powerfactor?
If power factor is increased, current will be reduced for a specific real power (kWs) relative to before. Total power is real power plus the vector of reactive power (you have to do polar math). So total current = (current from real power) + (current from reactive power). By changing the power factor, you decrease the second quantity. Go to Wikipedia.com and search for Power Factor if you need a more extensive description.
How many amps are in 1900 watts at 110 volts?
Depends on the supply voltage. For UK 230 Volts, 1800 Watts would mean the current drawn was 7.83 Amps.Watts=Volts x Amps, so Watts divided by Volts gives the current in amps.
How Core Loss is dependent on Frequency?
since at no load only excitation current(responsible for core loss ie iron loss) flow on the primary side so core loss current will be 1A and core loss = v1*i1*powerfactor. core loss = 1*11000*0.24= 2640watt.
How many watts are in 125 volts?
These are not convertible quantities. The same way that you cannot convert seconds into pounds. Or pounds into miles per hour. If you reconstituted your question into the form of "I have a device that draws 2 amps at 125 volts, how many Watts is it consuming?" we'd be off to the races. Hope that helps.
