B. Variable Resistors
Variable resistors allow users to adjust their resistance value, making them versatile components in electronic circuits.
1. **Potentiometers**: These three-terminal devices are commonly used to adjust voltage levels in circuits, such as volume controls in audio equipment. They can be linear or logarithmic in their resistance change.
2. **Rheostats**: A type of variable resistor, rheostats are used to control current in a circuit. They typically have two terminals and are often used in applications requiring high power.
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), photoresistors change resistance based on light intensity. They are often used in light-sensing applications, such as automatic lighting systems.
3. **Varistors**: Voltage-dependent resistors that change resistance with voltage fluctuations, varistors are used for surge protection in electronic circuits.
