RS PRO Potentiometer Caps


This Potentiometer from our own RS PRO brand is designed to be used for professional equipment to control electrical devices such as volume controls on audio equipment.

Features & Benefits


• Resists shock, vibration, or accidental movement
• No special mounting hardware or tools required
• Made of highest quality materials
• Occupies minimum panel space

Applications


There are many different uses of a potentiometer. The three main applications of a potentiometer are:

• Comparing the emf of a battery cell with a standard cell
• Measuring the internal resistance of a battery cell
• Measuring the voltage across a branch of a circuit

How does potentiometer work?


Most potentiometer knobs are simply fixed on manually with a simple push by fitting it to the shaft. They either have a knob, screw, grub, or slider as a fixture that is used as a control element to vary the resistance between the middle terminal and either one of the outer terminals for the potentiometer.
