Assalamu Alaikum,

I hope everyone is very good. I came to you about something about electronics. Let’s start talking without talking. We will know about the capacitor today.

What is capacitance and capacitor?

Capacitance: Capacitance is a multiplication of electric circuit, which prevents the change of voltage.

Capacitor: It is called capacitor when two parallel conductors are separated by an electrometer.

Two types of capacitors:

1 / variable capacitor

2 / unchanging capacitor.

1 / Dynamic Capacitor: The capacitor that changes the value is called a variable capacitor.

2 / irreversible capacitor: The capacitor does not change the value, it is called an irreversible capacitor.

The irreversible capacitor is again divided into several parts. Such as:

A / glass b / mica c / air

D / polyester e / paper c / ceramic

G / oil j / electrolytic etc.

Variable capacitors are two types. Such as:

1 / gang capacitor

2 / Trimmer capacitor.

Gang Capacitor: In the capacitances that are connected to multiple variable capacitors and are effective,

The gang is called a capacitor.

Trimmer Capacitor: Trimmer capacitor is a small capacitance with variable capacitor which has two points.

Capacitance unit: Farad is the largest unit of capacitor. Microphysarized as a small unit, nanofarad,

Picoferrad

We know

1 Farad = 106 microfarride

= 109 nanofarad

= 1012 picoferrad

The use of variable capacitors and continuous capacitors is given.

“Use of variable capacitor”:

* To tune the radio receiver station.

* For the purpose of fine tuning at Radio Frequency Stage

* Aluminum is used in the coule.

“Use of continuous capacitor”:

* Filtering for non-fake dc.

* To measure very little electricity flow.

* To keep electric circuits sparkless.

What is the capacitor color code?

The capacitor has the capability to mark the capacitor’s value by specifying the color of the capacitor color code.

Below are the capacitor color codes used:
Color Black Brown Red Orange Yellow Green Blue Purple Bright White
The first letter is la ka ha ne ni bay da sa
Value 0 1 2 3 4 5 6 7 8 9
Tolerance ± 20% ± 1% ± 2% ± 2.5% x ± 5% x x ± 10%
Voltage x x 250v x 400v x x x x x

Value Outward Sue: ABx10c ± D, E
