2. **Rheostats**: Similar to potentiometers but designed to handle higher currents, rheostats are used for controlling current flow in applications like lighting and motor speed control.
C. Specialty Resistors
Specialty resistors are designed for specific applications and include:
1. **Thermistors**: Temperature-sensitive resistors that change resistance with temperature variations, thermistors 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, making them ideal for light-sensing applications.
