Resistive Loads
Resistive Loads are any electrical device that consisting of heating
element, and working based on the Resistances Working principle.

4. 4
Inductive Loads
An Inductive Loads converts current into a magnetic field.

5. 5
Inductance
In electromagnetism and electronics, Inductance is the tendency of
an electrical conductor to oppose a change in the electric current
flowing through it. The flow of electric current creates a magnetic
field around the conductor.

Inductive Reactance
Inductive Reactance is the name given to the opposition to a
changing current flow. This impedance is measured in ohms, just like
resistance.
𝑋𝐿 = 2𝐹𝐿

7. 7
Capacitive Loads
Capacitive Loads include energy stored in materials and devices,
such as capacitors, and cause changes in voltage to lag behind
changes in current.

Average Power
Average Power is the average of instantaneous power over one
period.

Power Factor
The ratio of real power to apparent power provides us with an
important quantity called Power Factor.

Lagging Power Factor
A load in which the current lags the applied voltage is said to have a
Lagging Power Factor.

Leading Power Factor
A load in which the current leads the applied voltage is said to have
a Leading Power Factor.
