II. Overview of Resistor Types
A. Fixed Resistors
Fixed resistors have a constant resistance value and 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 tolerance and ability to withstand high temperatures. However, they are less stable than other types and are often used in applications where precision is not critical.
2. **Metal Film Resistors**: These resistors are made by depositing a thin layer of metal onto a ceramic substrate. They offer better stability and accuracy than 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.
B. Variable Resistors
Variable resistors allow for adjustable resistance values, making them versatile components in electronic circuits.
1. **Potentiometers**: These are three-terminal devices that can adjust voltage levels in a circuit. They are commonly used in volume controls and other applications where variable resistance is needed.
2. **Rheostats**: Similar to potentiometers but typically used for higher current applications, rheostats allow for the adjustment of current flow in a circuit.
C. Specialty Resistors
Specialty resistors are designed for specific applications and have unique properties.
1. **Thermistors**: These temperature-sensitive resistors change resistance with temperature variations. They are commonly used in temperature sensing and control applications.
2. **Photoresistors**: Also known as light-dependent resistors (LDRs), these components change resistance based on light intensity. They are often used in light-sensing applications.
3. **Varistors**: Voltage-dependent resistors that change resistance with voltage fluctuations, varistors are used for surge protection in electronic circuits.
