Brief trimmer potentiometer trimpot variable resistor voltage divider circuit fragment

Table of Contents

Potentiometers are three terminal devices. Two terminals are the ends of a fixed resistive element. The third terminal is a wiper that makes an electrical connection to a variable point along the resistive element. The exact point the wiper connects to the resistive element depends on where the dial/screw driver slot is turned to.

If I buy more trimpots it will probably be these. There’s some that are a dollar cheaper at this time but they are almost sold out. Clicking this link will likely show them somewhere on the page too if they are in stock.

Trimmer potentiometer (trimpots) are small versions of potentiometers. They often fit in breadboards really easily and are very common now.
