What is Potentiometer – Best knowledge of Potentiometer class 12

Hello friends, if you want to master electrical or electronics, then you should have knowledge of all things, and for this, you will have to study, but despite many courses, there are some things about which to get the right information. It is very difficult, and that is why we have created this website where you get all kinds of information like Potentiometer, Motor, etc. in detail.

And in today’s lakh we are going to know about Potentiometer, we will tell you what is Potentiometer, where it is used, how it is made, and angles are used, so stay with us And if you like this article, then do share it with your friends.

What is a potentiometer used for?

This is a divider which is used to control the current flow, but this is not the only use of Potentiometer.

Potentiometer is also used on many other wakes, it can be said that it is a kind of force control tool, which is used for different tasks on different wakes.

A Potentiometer can be of many types and can also be made for many different tasks, Potentiometer is used to reduce or control any kind of force.

It is mostly seen in electrical devices where it is used to control the electric current, if we talk about where the potentiometer is used then it is very difficult to say, because it is used on many wakes. Is. Still, I have given some list in which Potentiometer is used.

What is potentiometer simple words?

In simple words Potentiometer is a device which is measuring electric current, this is a voltage divider.

What is an electrical potentiometer?

Potentiometer is an electrical part which is used on many awakenings, it is a controllable resistor, which does not run the risk of getting a shock while using it and you can control the current flow comfortably.

Potentiometer is seen in most of the music systems by which we control the volume, and it helps us to provide as much current as we need, it is a device without which many tasks in our life can be incomplete. Is.

But this Potentiometer is not a remote control, it is operated only manually, in the olden days it was used a lot, because then remote control technology had not emerged and even if it did, it did not become so famous.

There are many types of Potentiometer, some of which are such Potentiometer model, whose list is given below, how you can know more about them.

Types of Potentiometer.

  • Rotary potentiometers
  • Linear potentiometers
  • Digital potentiometers

Rotary potentiometers

  • Single-turn pot

Single gyration of Potentiometer roughly 270 degrees or3/4 of a full turn.

Most common pot, used in operations where a single turn provides enough control resolution.

  • Multi-turn pot

Multiple Reels( substantially 5, 10 or 20), for increased perfection. They’re constructed either with a wiper that follows a helical or helix form or by using a worm- gear.

Used where high perfection and resolution is needed. The worm-gear multi-turn pots are frequently used as trim pots on PCB.

  • Binary- gang pot

Two potentiometers combined on the same shaft, enabling the resemblant setting of two channels. Most common are single-turn potentiometers with equal resistance and taper. Further, than two gangs are possible but not veritably common.

Used in for illustration stereo audio volume control or other operations where 2 channels have to be acclimated in parallel.

  • Concentric pot

Binary potmeter, where the two potentiometers are collectively acclimated by means of concentric shafts. Enables the use of two controls on one unit.

Frequently encountered in (aged) auto radios, where the volume and tone controls are combined.

  • Servo pot

A motorized potmeter which can also be automatically acclimated by a servo motor.

Used where homemade and automatic adaptation is needed. Frequently seen in audio outfit, where the remote-control can turn the volume control clump.

Linear potentiometers

  • Slide pot

Single direct slider potentiometer, for sound applications otherwise called a fader. Great faders are regularly built from conductive plastic.

For single channel control or estimation of distance.

  • Double slide pot

Double slide potentiometer, single slider controlling two potentiometers in equal.

Frequently utilized for sound system control in proficient sound or different applications where double equal channels are controlled.

  • Multi-turn slide

Developed from a shaft which incites a direct potentiometer wiper. Various turns (generally 5, 10 or 20), for expanded accuracy.

Utilized where high accuracy and goal is required. The multi turn straight pots are utilized as trimpots on PCB, yet not generally so normal as the worm-gear trimmer potentiometer.

  • Mechanized fader

Fader which can be naturally changed by a servo engine.

Utilized where manual and programmed change is required. Normal in studio sound blenders, where the servo faders can be consequently moved to a saved design.

Digital potentiometers

Digital potentiometers are potentiometers that are controlled electronically. In most cases, they exist as an array of small resistive components in series. Every resistive element is equipped with a switch that can serve as the tap-off point or virtual wiper position. A digital potmeter can be controlled by for example up/down signals or protocols like I²C and SPI.

How does a Potentiometer work?

There is a resistor plate inside a potentiometer which is connected with the left and right pins, and the middle point is used to control the current flow, and you all know that a positive and a negative are complete into a circuit.

So here also the same formula is used, neutral is added to the right side point, a positive current is added to the left side point, after that the middle point is passed over that positive resistor plate so that Friction is created in the existing current flow, and that’s it Potentiometer provide the same flow the amount of current that is we needed, if we remove the neutral point then the potentiometer will not work.

Apart from this, it is special information for all the people who always do some extraordinary experiments, if you think that if we reverse the current connection, will it work? So in response to this, we will say that it will definitely work, but on the contrary, you will have to rotate the Potentiometer upside down.

Often we get to see this Potentiometer in our homes which we use since our childhood, but do you know how effective this small device is in our daily life? If you know this, then definitely tell us by commenting.

How to make Potentiometer at Home?

To make a Potentiometer at home you need some electronics parts name is a resistance plate, rotation saft, Cap, soldering iron, Wire. all these parts you can buy from an electronics store or an online shopping site.

Now lets’s start making a Potentiometer. remember this is very simple and easy to make, and if you are a student and want to know how to make Potentiometer at home then buy the listed parts, and if you are a professional then it better is to buy a complete Potentiometer this is better for you.

  • Put the resistance plate inside of the Cap.
  • Now put the saft & close the cap.
  • That’s it your Potentiometer is ready to use.

And if you want to make an old model Potentiometer at home then you need to make a coil you can get an example from a ceiling fan regulator.

  • Create a coil using copper wire and make your speed points.
  • Now get a switch and connect it to the speed points.
  • Your old model Potentiometer is ready to use.
