Best Answer

A transformer would be an inductive load. The coil of a relay would be an inductive load. Inductive loads use magnetic fields, ie motors, solenoids and relays. Capacitive loads are ones that capacitance exceeds inductance. ie flash on camera.

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.

A transformer is fundamentally a set of coils; therefore, a transformer is an inductive load. However, by "transformer load", you seem to mean "the load that is connected to a transformer". Whether that load is inductive or capacitive depends mostly on what is hooked up to the transformer.

Inductive reactance is traditionally positive while capacitive reactance is traditionally negative. Those are the conventions used by electrical engineers and they are consistent with a time-dependency of exp(+jwt).

In capacitive coupling, there is usually a dielectric between the electrodes, whereas in inductive coupling, the plasma is created by a magnetic field with a coil. Capacitive coupling is used for low power, low density, and high plasma potential. And inductive coupling is used for high power, high density, low plasma potential.

The terms, 'lagging' and 'leading', describe the relationship between a circuit's load current and supply voltage. They describe whether the load current waveform is leading or lagging the supply voltage -always the current, never the voltage. Inductive loads always cause the current to lag the supply voltage, whereas capacitive loads always cause the current to lead the supply voltage.

Inductive loads involve devices which establish magnetic fields. Capacitive loads involve devices which establish electric fields. Another way of looking at it is that inductive loads have a lagging power factor, whereas capacitive loads have a leading power factor.

Capacitive loads have a leading power factor. Current leads voltage when there is capacitive reactance. (The opposite is inductive, which is lagging.)

non- inductive load is without motor and transformer loads are non-inductive load, purely resistive are capacitive loads phase angle is unity are leading PF A non-inductive load is a load whose current does not change instantaneously.

Susceptance is the reciprocal of reactance, and is expressed in siemens (symbol: S). So, inductive susceptanceis the reciprocal of inductive reactance, and capacitive susceptance is the reciprocal of capacitive reactance.

Most loads are actually resistive, such as an incandescent (normal) light bulb or electric heat or cooking equipment. Other loads are mostly inductive because they incorporate either transformers or motors, which are both inductive. Off hand I cannot think of a normally capacitive circuit, which would be the opposite of inductive.

No, inductive

It isn't necessarily so. The capacitive voltage is the product of the current and capacitive reactance, while the inductive voltage is the product of the current and the inductive reactance. So it depends whether the capacitive reactance is greater or smaller than the inductive reactance!

Inductive reactance.
