## What is a potentiometer?

Potentiometers are commonly used for various purposes, including volume control in audio devices, brightness control in displays, and position sensors in robotics and industrial applications. They provide a simple and convenient way to vary the resistance and adjust the output of a circuit to meet specific requirements.

A potentiometer, also known as a variable resistor/pot, is an electronic component that allows for the adjustment of electrical resistance in a circuit. It consists of a resistive track or strip made of a material with high resistivity, such as carbon/metal. The resistive track has three terminals two fixed terminals and a third terminal called the wiper/slider.

**Formula:**

V_{L}= (R_{2}R_{L}/ (R_{1}R_{L}+R_{2}R_{L}+R_{1}R_{2})) × Vs

## How to find a potentiometer?

**Example 1:**

Determine the potentiometer if

R_{1} (amps) = 13

R_{2} (amps) = 12

r_{l} (amps) = 23

Vs(volts) = 10

**Solution**

**Step 1:**

**The formula for the potentiometer is given below:**

V_{L}= (R_{2}R_{L}/ (R_{1}R_{L}+R_{2}R_{L}+R_{1}R_{2})) × Vs

**Step 2:**

**Replace the values**

V_{L} = (12 × 23/ (13 × 23+12 × 23+13 × 12)) × 10

**Step 3:**

**Simplifying the values **

V_{L} = (276 / (299+276+156)) × 10

V_{L} = (276 / 731) × 10

V_{L} = 0.3775 × 10

V_{L} = 3.775

**Example 2:**

Determine the potentiometer if

R_{1} (amps) = 25

R_{2} (amps) = 15

r_{l} (amps) = 10

Vs(volts) = 5

**Solution**

**Step 1:**

**The formula for the potentiometer is given below:**

V_{L}= (R_{2}R_{L}/ (R_{1}R_{L}+R_{2}R_{L}+R_{1}R_{2})) × Vs

**Step 2:**

**Replace the values**

V_{L} = (15 × 10/ (25 × 10+15 × 10+25 × 15)) × 5

**Step 3:**

**Simplifying the values **

V_{L} = (150/ (250+150+375)) × 5

V_{L} = (150/775) × 5

V_{L} = 0.19354 × 5

V_{L} = 0.96774
