2. Types of DC Resistors
There are several types of DC resistors, including:
Fixed Resistors: These have a constant resistance value and are commonly used in circuits.
Variable Resistors: Also known as potentiometers, these allow users to adjust resistance levels.
Specialty Resistors: These include thermistors and photoresistors, which change resistance based on temperature or light exposure.
B. Applications of DC Resistors
DC resistors are utilized in a wide range of applications:
1. Industrial Uses
In industrial settings, DC resistors are used in motor control circuits, power supplies, and load testing. They help manage energy consumption and ensure the safe operation of machinery.
