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.

Power factor is determined by the nature (resistive, inductive, capacitive) of a load, not whether it is a low load or a high load.

the inductive load which is generally use in high voltage transmission line known as transformer. the transformer transform the high voltage to low voltage.

Yes because the transformer heating (power losses) depend on the load current and the load voltage. It can be assumed that the voltage stays more or less constant, therefore the iron loss is also constant. The copper loss depends on the square of the load current. So it is the VA of the load that determines the power loss and any heating.

This means there is a reactive component, either inductive or capacitive, to the load.

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.

example capacitive load

No because the very first component in the power supply is a transformer, which makes for it being an inductive load.

Inductive load means lags behind the voltage, where as capacitive load means lead behind the voltage.

No

Resistive load ,Capacitive load,Inductive load

Yes, transformer losses will be the same for any linear load with the same VA. However, if the load is nonlinear, such as a rectifier, the load waveform will be distorted and the losses will be higher than with an undistorted sinusoidal load current of the same VA

For an inductive load, the current lags the voltage by 90 degs. Hence the power factor for an inductive load is 0. For a capacitive load, the current leads the voltage by 90 degs. Hence the power factor for a capacitive load is 0. For a resistive load, the current and the voltage are in phase. Hence the power factor for a resistive load is 1.

A purely resistive load is one in which there is no capacitive or inductive reactance. Whe driven by an AC voltage source, such a load will have no shift in phase angle between voltage and current.
