1M Potentiometer B1M - 20cm

 A potentiometer, often referred to as a "pot", is a type of variable resistor. It is designed with a movable contact, known as a wiper, that slides or rotates along a resistive element, forming an adjustable voltage divider. The wiper's position along the resistive element can be altered, which in turn adjusts the resistance between the wiper and one or both ends of the resistive element. This change in resistance modifies the output voltage or current. 

Types of Potentiometers

 Potentiometers are available in a variety of forms, including rotary (circular) and linear (straight-line) models:

• Rotary Potentiometers: These are typically used in scenarios where continuous rotation is necessary to alter the resistance value. Examples include volume controls on audio devices or tuning knobs on radios.
• Linear Potentiometers: These are often employed in situations where the resistance needs to be adjusted along a straight path. They are commonly found in sliders on mixing consoles or in position sensors.

Applications of Potentiometers

 Potentiometers are extensively utilized in electronic and electrical circuits for a variety of purposes, such as:

• Volume Control in Audio Equipment: Potentiometers are frequently used to regulate the volume of speakers or headphones.
• Brightness Control in Displays: They can be used to modify the brightness of displays like LCDs or LED panels.
• Motor Speed Control: In motor control circuits, potentiometers are used to change the speed of DC motors.
• Tuning and Frequency Adjustment: Potentiometers are employed in radios and other communication devices to tune to different frequencies or adjust the frequency of oscillators.
• Sensing and Measurement: Potentiometers can act as sensors to measure the position, angle, or displacement of mechanical components.

In conclusion, potentiometers are multifunctional components that are used in a broad spectrum of electronic devices and systems.
