answer:-- What is the meaning of capacitive and inductive current? How are they different from 'normal' current?

There are 3 types of loads and when connected to AC they show different characteristics.

Inductive and capacitive loads have an effect on AC current and voltage that is not seen with a steady DC source.

Inductive loads oppose a change in current. The voltage increases immediately but the current takes time too change depending upon the inductive value of the inductor. In the same manner when the current reduces the inductor tends to oppose the change. This is called inductive reactance (Xl). So the current lags behind the voltage. Inductive loads are most common . They include motors and transformers amongst many others.

Capacitive loads show a leading current, The current in a capacitor is maximum initially and reduces as the voltage across the capacitor charge increases. This is called capacitive reactance (Xc). So the current leads the voltage.

Capacitors are used frequently to correct a poor power factor due to a high proportion of inductive loads connected to an AC system.

Purely resistive loads have no reactive effect on AC. The current is in phase with the voltage.

Most loads consist of resistance and inductance combinations with capacitors often included to improve the power factor of a single accessory or fitting. You can see this commonly in discharge lighting like old fluorescent, mercury vapour and sodium vapour lamps.

A word about power factor. This describes the amount of current lag or lead that is shown in a load. The ratio of multiplying the Volts x Amps and then comparing to the true power meter reading determines the power factor. The VxA is higher than the watts measured by a power meter. The power meter only measures the in phase portion of the Volts and Amps. The aim is to keep that ratio at about 0.8 to 0.9.
