I. Introduction

I. Introduction

In the world of electronics, adjustable resistors play a crucial role in circuit design and functionality. These components allow engineers and hobbyists to fine-tune resistance values, enabling precise control over current flow and voltage levels. This article aims to explore the pricing of popular chip adjustable resistor models currently in stock, providing insights into their specifications, applications, and where to purchase them.

II. Understanding Adjustable Resistors

A. Explanation of Adjustable Resistors and Their Functionality

Adjustable resistors, commonly known as variable resistors, are components that allow the resistance to be changed manually or electronically. The two primary types of adjustable resistors are potentiometers and trimmers.
