13. Capacitor
• A capacitor (originally known as a condenser) is a passive two-
terminal electrical component used to
store energy electrostatically in an electric field.
• The forms of practical capacitors vary widely, but all contain at least
two electrical conductors (plates) separated by
a dielectric (i.e., insulator).
• The conductors can be thin films of metal, aluminum foil or disks,
etc. The 'nonconducting' dielectric acts to increase the capacitor's
charge capacity.
• A dielectric can be glass, ceramic, plastic film, air, paper, mica, etc.
Capacitors are widely used as parts of electrical circuits in many
common electrical devices.
• Unlike a resistor, a capacitor does not dissipate energy. Instead, a
capacitor stores energy in the form of an electrostatic field between
its plates.

14. • Capacitors can be useful for storing charge
and quickly discharging into the load. In a
simple way, a capacitor also work as a small
rechargeable battery. The electrical
equivalent symbol of different types of
capacitor is given below:

18. INDUCTOR
• In inductor is a passive electronic component which is capable of
storing electrical energy in the form of magnetic energy.
• An inductor is a coil of wire around a central core that can consist of a
variety of materials. Hence, inductors are also known as a coil or a
reactor. If an electric current flows through this coil of wire it produces
a magnetic field around it. The strength of the magnetic field induced
by the electric current flowing around the central core depends on the
type of material of the core, the number of coils of the wire, and the
cross-sectional area and length of the coil.
• For example, if the central core was also magnetic, the magnetic field
around the inductor will be a lot stronger. Inductors are a very
important component in electronic circuits because they're able to resist
or oppose changes of current in the circuit.

An inductor works by inducing a magnetic field as an electric
current flows through its coil of wire. This magnetic field
temporarily stores electric energy as magnetic energy, creating a
voltage across the inductor.
The strength of the magnetic field or the inductance of the
inductor is dependent on a variety of properties such as the
number of coils in the wire, the cross-sectional area of the
inductor, and the type of material the inductor's core is made out
of.
The inductance (L) of an inductor is given in units of Henry, after
the physicist Joseph Henry.
