No, as 100% efficiency is not possible.
AnswerYes, it occurs at resonance. That is, when a circuit's inductive reactance is exactly equal to its capacitive reactance. This can be achieved by adjusting the frequency of the supply until resonance is achieved. Incidentally, power factor has nothing to do with 'efficiency'.

How do you calculate power factor kvr?
Power Factor = KVA/KW. This has no unit. Its value is always 1 or less.
Power factor for pure resistive circuit?
ratio between true power and apparent power is called the power factor for a circuit Power factor =true power/apparent power also we conclude PF=power dissipated / actual power in pure resistive circuit if total resistance is made zero power factor will be zero
Why Voltage x Current do not equal rated power?
In an AC system power is equal to Voltage x Current x Power factor. Power factor is not constant and depends on the type of the load. Ideal value of the Power factor is 1, where as practically remains less then 1.
What is meant by unity power factor?
when voltage n current r in same phase(it happens when load is resistive) ,the power factor which denoted by "fi" is 1 .this condition is known as unity power factor
What does unity power factor UPF mean?
Unity power factor has a value of 1.0. This means the current and voltage waveforms are in phase. This is only possible if the net load is non-reactive (resistive). If the load is either capacitively or inductively reactive, the power factor will be other than unity. If an inductively reactive load such as a motor is offset by a capacitively reactive load such as a PF correction capacitor, it is possible to acheive a net load that has unity power factor. Some loads, such as resistance heaters, are intrinsically non-reactive, and present a unity power factor.
Can power factor greater than 1?
not possible. power factor is an cosine angle between current and voltage...
Is it possible for generators having different power factor to work together?
yes, it is possible. in fact in power systems all the generators do not run with same power factor.
What is standard power factor value?
The power factor measures the phase difference between a current and a voltage waveform. Power factor ranges from zero to one. A power factor of 1 is for a pure resistive load. Power factor decreases for loads like motors with high inductance. Power factor comes into play when determining the watts used by a device. Watts = Volts x Amps x PF. So ideally for efficiencies sake, you want to keep the PF as close to one as possible.
Is it possible to measure the power factor of the balanced?
Of the 'balanced' what?
Is it possible to transmit power with leading power factor?
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.
What is the power factor of AC generator when the reactive power is equal to zero?
Per factor is 1 when reactive power is zero.
Why should always be power factor less than 1?
Power factor can also be equal to 1. Power is greatest when voltage and current are in phase; the "power factor" is used to specify how much less the power is, compared to the product of voltage x current, if they are not.
What is the power factor of pure resistor?
1

How many kilowatts in 1kva?
Its a bit of a trick question. 1 watt is one volt-amp except in situations where the power factor has increased or decreased that ratio. For instance with a power factor of .8 a volt-amp is equal to .8 watts. So with a perfect power factor 1 kva (kilo-volt-amp) is equal to 1 kilowatt. But if the power factor is something other then 1 you can find it by pf*w=va.
