Capacitor is

Capacitor has many names such
as condenser (condenser) / Capa

Capacitor translated into Thai

means Capacitor is an electronic

device that is widely used. It is

properties of inductors Therefore,
middle. they are often used to contradict or
work together in different circuits. It
is one of the three linear passive
components that make up the circuit.
In the power supply system, many
capacitors are used in series to
increase the power factor (Power
factor) to the electrical system
called Cap Bank. Some capacitors in
the future have a high probability of
being Used instead of batteries such
as super capacitors.

Construction

Capacitor with polarity and without polarity

Capacitor type We can divide it in many ways. Here, we will divide by pole.
- with polarity in this way, when using, it must be connected to the right polarity
only. We can find it in a circuit that is direct current.
- without polarity this will allow the system to control the forwarding data stream
without looking at the abstract.

What are capacitors made of?

Capacitors are important devices in

electrical circuits and controls are

made of two conductive plates

(parallel conductive plates)

sandwiched between them by a

dielectric for the composite plate of

the sample, like the sandwich shown

in the figure.

PRESSURE RESISTANCE

The voltage resistance is measured in Volt (V).
Read that Volt is the capacitor value. will be able
to continue using in purchase to replace or
repair We must hold on to the original value, not
less than but more if the value is greater The
price will be higher. If it is a very active design, it
will be reserved twice, for example, a capacitor in
a home fan motor. can see that most of them
use 450V (electricity 220 x 2 = 440V)

The bottom level is Collect that will collect the plates of the plates. which will
bring the battery to connect with the electromagnet from the negative pole
of the battery to join the plate which causes the negative beam to rise and
transmit the electric field Assembly blade The opposite plates in which the +
and - plates come together. When electrons from this plate are pushed out
and left with more positive charges than negative charges The more
electrons that are ejected, the more The more positive the plate becomes.

charged capacitor If we do not connect the capacitor terminals together. The electrons
remain on the plate. But if there is a full cycle between the two plates when Electrons will
flow from the negative plate. to complete the cycle at the positive plate immediately, we
call it "discharge"

principle

PRINCIPLE

The working principle of Capacitor or
capacitor is when the capacitor is connected
to the circuit or complete power supply. We
can observe that the current cannot flow
through the capacitor (looked as an Open
Circuit) because the capacitor has an
insulator.

At the same time, an electric charge that cannot cross the insulator is formed on
the conductor plank. causing that side to have a lot of negative electric charge
(Electron) On the other hand, the conduction plan on the opposite side becomes a
positive charge because many electrons flow to the other side. The charge
attached to the conductor plan of the capacitor is because Each side has electric
charges that are of opposite polarity, creating an electric field that attracts each
other (+ and – attracts each other), which allows the capacitor to store potential
energy or voltage (Voltage).
