What are the Popular Models of Resistors in Circuits? I. Introduction Resistors are fundamental components in electrical circuits, serving the essential function of controlling the flow of electric current. By providing resistance, they help to manage voltage levels, protect sensitive components, and ensure that circuits operate efficiently. This article will explore the various models of resistors commonly used in circuits, their characteristics, applications, and the factors that influence their selection. II. Basic Concepts of Resistors A. Ohm's Law At the heart of understanding resistors is Ohm's Law, which states that the current (I) flowing through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) of the conductor. The formula is expressed as: \[ V = I \times R \] This relationship is crucial for designing circuits, as it allows engineers to calculate the necessary resistance to achieve desired current and voltage levels. B. Types of Resistance Resistors can be categorized into two main types: fixed and variable. 1. **Fixed Resistors**: These resistors have a constant resistance value and are widely used in circuits where a specific resistance is required. 2. **Variable Resistors**: Also known as potentiometers or rheostats, these resistors allow for adjustable resistance, making them ideal for applications such as volume controls in audio equipment. III. Popular Models of Resistors A. Carbon Composition Resistors Carbon composition resistors are made from a mixture of carbon particles and a binding resin.
