II. Types of Resistors
A. Fixed Resistors
Fixed resistors have a constant resistance value and are the most commonly used type in electronic circuits. They come in various materials and constructions, including:
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 lower stability compared to 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, making them suitable for precision applications.
3. **Carbon Film Resistors**: Similar to metal film resistors, carbon film resistors are made by depositing a thin layer of carbon. They provide a good balance between cost and performance, making them popular in various applications.
4. **Wirewound Resistors**: Constructed by winding a metal wire around a ceramic or plastic core, wirewound resistors can handle high power levels and are often used in high-frequency applications.
B. Variable Resistors
Variable resistors allow for adjustable resistance values, making them versatile for various applications.
1. **Potentiometers**: These are commonly used for adjusting volume in audio equipment and tuning in radios. They consist of a resistive element and a wiper that moves along the element to change the resistance.
2. **Rheostats**: Similar to potentiometers but typically used for higher power applications, rheostats allow for the adjustment of current flow in circuits.
C. Specialty Resistors
Specialty resistors are designed for specific applications and include:
1. **Thermistors**: Temperature-sensitive resistors that 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 resistors change resistance based on light exposure. They are commonly used in light-sensing applications.
3. **Varistors**: Voltage-dependent resistors that protect circuits from voltage spikes. They are often used in surge protection devices.
