II. Types of Resistors
A. Fixed Resistors
Fixed resistors have a predetermined resistance value that cannot be changed. They are widely used in electronic circuits.
1. **Carbon Composition Resistors**: Made from a mixture of carbon and a binding material, these resistors are known for their high energy absorption and ability to withstand high temperatures. However, they have a higher tolerance and are less stable than other types.
2. **Metal Film Resistors**: These resistors are made by depositing a thin layer of metal onto a ceramic substrate. They offer better stability, lower noise, and tighter tolerances compared to carbon composition resistors, making them suitable for precision applications.
3. **Wirewound Resistors**: Constructed by winding a metal wire around a ceramic or fiberglass core, wirewound resistors can handle high power levels and are often used in power applications. They are known for their accuracy and stability.
B. Variable Resistors
Variable resistors allow users to adjust the resistance value as needed.
1. **Potentiometers**: These are commonly used for volume control in audio equipment and as adjustable voltage dividers in circuits. They consist of a resistive element and a movable contact.
2. **Rheostats**: Similar to potentiometers but typically used for higher power applications, rheostats allow for the adjustment of current flow in a circuit.
C. Specialty Resistors
Specialty resistors are designed for specific applications.
1. **Thermistors**: These temperature-sensitive resistors change resistance with temperature variations. They are widely used in temperature sensing and control applications.
2. **Photoresistors**: Also known as light-dependent resistors (LDRs), these components change resistance based on light exposure. They are commonly used in light-sensing applications, such as automatic lighting systems.
