Understanding and functioning of resistors

If you are a beginner in the field of electrical, you may ask what is the definition of resistor? How do resistors work? How do you calculate resistor value? What are the functions of resistors in electric circuits? we will discuss it Now

If an electric current flows through a resistor, it can be detected that the electric current will be small because it will be interrupted.

For example, if an electric current passes through a resistor, for example the initial current value is 1A, then the current after passing through the resistor will be small and less than 1A.

If the resistor is high, the current will be small and vice versa. If the resistor is small, the current will be even more.

Now the size of resistance is determined by the color rings on body of the resistor. The resistive value is calculated in

So now we know what is a resistor

Now, when we know about the understanding of resistors, please continue reading about the function of resistors in electric circuit.

An example of a resistor function as a current resistor is that you can find it on the indicator light. If you open a socket where you have an LED light, you will find a resistor inside. The resistor functions as the current barrier of the LED lamp, so it does not burn. If the resistor is removed, the LED light will light up because the LED will not pass when a large current is passed.

The Value of these colors are as following:-

Black = 0

Chocolate = 1

Red = 2

Orange = 3

Yellow = 4

Green = 5

Blue = 6

Purple = 7

Gray = 8

White = 9

Gold = 5%

Silver = 10%

Colorless = 20%

How to calculate the resistor value, you should know the foot first. Remember not to reverse!

The characteristics of the first ring is closest to the wire. The final ring features gold, silver or colorless.

First ring first number.

The second is to determine.

The ring is to determine the second value of the third ring to determine the number of zeros. The fourth ring has to determine the tolerance value of the resistor.

In the example of a resistor, the color of the Ring is as follows. What is the value of resistor?

How to understand resistor and calculate resistor values

First ring = brown = 1

Second ring = green = 5

Third ring = red = 2

Fourth ring = gold = 5%

So the size of the resistor above is 1500 + 5% = 1.5k + - 5%

The inhibitor described above is a type of fixed inhibitor. Now apart from this, there are still other types of resistors that you need to know

### What is register ??

You need to know that resistors are passive electronic components that act as current resistors.If an electric current flows through a resistor, it can be detected that the electric current will be small because it will be interrupted.

For example, if an electric current passes through a resistor, for example the initial current value is 1A, then the current after passing through the resistor will be small and less than 1A.

If the resistor is high, the current will be small and vice versa. If the resistor is small, the current will be even more.

### Function of resistors in electrical circuit

The basic current of resistor function in electrical circuit is as resistor.An example of a resistor function as a current resistor is that you can find it on the indicator light. If you open a socket where you have an LED light, you will find a resistor inside. The resistor functions as the current barrier of the LED lamp, so it does not burn. If the resistor is removed, the LED light will light up because the LED will not pass when a large current is passed.

**How to calculate resistor value ?****The resistor consists of colored rings indicating the value of resistance of a resistor. Each color ring has its own value.**

The Value of these colors are as following:-

Chocolate = 1

Red = 2

Orange = 3

Yellow = 4

Green = 5

Blue = 6

Purple = 7

Gray = 8

### Fixed resistor

A fixed resistor is a resistor that has a fixed resistance value as described above.###
**Variable resistor**

In simple language*A variable resistor is a resistor whose resistance value can be changed. An example of a variable resistor is a potentiometer (VR) that you can find on an amplifier. The resistance or resistance values on the potentiometer can be changed by changing the potentiometer. Also read how to install a potentiometer*### LDR (Light Dependent Resistor)

**LDR**is a type of resistor whose resistance value can vary according to the intensity of the light that receives it. The use of LDR can be found on highway lighting lamps where the lights will turn on automatically when it is dark and turn off when it is bright.read this also

### How does this LDR work ?

Perform simple automatic illumination using LDRPTC and NTC

**PTC (positive temperature coefficient)**is a type of resistor whose resistance value changes due to the temperature it receives. PTC resistance will be higher when temperature is high and resistance will decrease when temperature is low.**NTC (negative temperature coefficient)**is a resistor whose resistance value decreases when the temperature increases and the resistance will increase as the temperature increases. So NTC is unlike PTC.
