I believe you're referring to reactive power. Reactive power is present any time the voltage and current are AC signals and not in phase. Some current simply charges and discharges the load reactance, and therefore does not deliver real power to the load.

How do you filter DC power?

D.C power can be filtered using low pass capacitive circuit


What are capacitive loads?

A load, at low frequencies, can be either capacitive, resistive, or inductive. At high frequencies, all three aspects exist. At low frequencies (say <= 10 MHz), a capacitive load is a capacitor, represented by an ideal cap, the MOScap, or a junction cap. An unintentional capacitive load would be the wire or conductor to another wire or conductor or ground. At high frequencies (say >= 1 GHz), all things have a capacitive nature. The higher the frequency, the worst is the capacitive leak A capacitive load means just that the load acts like a capacitor load as opposed to a inductor or resistive load


Which excitation synchronous motor drawn reactive power?

Hi, Under excitation - inductive reactive power Over excitation - Capacitive reactive power.


Is battery is inductive or capacitive load?

A battery is usually thought of as a source, not a load. If you are charging a battery, then it will be resistive, especially if you are attempting to charge it like you should, with a DC power supply (not AC).


What do you mean by wattless current and power factor in AC?

Watts = Current x Voltage x Power Factor In an AC circuit both the voltage and current are sine waves. When they are in phase (waveforms lie over top of one another) the PF is one. As they become out of phase the PF decreases to zero. This happens when the phase difference is 180 degrees. In this case the positive peak of current is at the same place in time as the negative peak of voltage or vice versa. So when PF is zero you coul say you are getting zero watts.AnswerAn a.c. load current can be resolved into two components. One, in phase with the supply voltage, and responsible for supplying true power to the load. The other, at right angles to the supply voltage, and responsible for supplying reactive power (e.g. the magnetic field, in the case of a motor). As reactive power is sometimes termed 'wattless power', we can say that the second component of this current is 'wattless current'.

What is the wattless current?

wattless current means that current by which no power is dissipated (Power=0).


What is meant by 'wattless power'?

Since reactive power transfers no net energy to the load, it is sometimes called "wattless" power.

Which watt meter used for capacitive loads?

Wattmeters are not used for loads which are purely capacitive or inductive, because no watts are consumed and no energy is consumed by the customer. But amps must still be supplied by the power company to supply the customer's capacitive or inductive load and the result is measured in volt-amps reactive (VAR), which can be registered on a meter called a reactive power meter. The ratio of watts to volt-amps is called the power factor (a capacitive load has a power factor close to zero). Industrial customers with a poor power factor are penalised with higher tariffs and encouraged to improve their power factor.


What is the power dissipated by a reactive load?

No power is dissipated by a load composed exclusively of either capacitive or inductive reactance.


What effect do var's have on the power factor of the circuit?

VAr is reactive power, caused by either inductive or capacitive loads. The ideal power factor to have is 1, anything less than that is a loss on the network. The effect of VArs on the circuit though depends. If you have a load that is mainly inductive, then adding more inductive reactance will lower the power factor. However, if you introduce capacitive reactance this will increase the power factor, and the opposite is true if its a mainly capacitive circuit. So VArs will either increase or decrease the power factor depending on the load of the circuit. The ideal situation is to balance inductive reactance with capacitive reactance so they in effect cancel each other out and power factor is 1.


What does watless mean?

The spelling closest to this word is wattless [two t's]. A wattmeter is an instrument for measuring electric energy and if there is none then it would be wattless. Wattles [with one s] are acacia trees indigenous to Australia.
