Fixed Resistors:
- These resistors have specific, unchangeable values.
- Common types include:
  - Carbon Composition Resistors: Made by sintering metal or metal oxide mixtures with glass on substrates like alumina.
  - Wire Wound Resistors: Constructed by winding wire around a ceramic rod.
  - Thin Film Resistors: Utilize thin film technology and are commonly surface mount type.
  - Thick Film Resistors: Also surface mount type and widely used in electronics circuits.
Variable Resistors:
- These resistors allow adjustment of resistance values.
- Types include:
  - Potentiometers: Used for volume and tone control in radio receivers.
  - Rheostats: Variable resistors with adjustable resistance.
  - Trimmers: Fine-tuning resistors for precise adjustments.
Non-Linear Resistors:
- Their resistance values change based on temperature and voltage.
- Examples:
  - Thermistors: Sensitive to temperature changes.
  - Varistors: Used for surge protection.
  - Photoresistors (LDRs): Vary resistance with light intensity.
Resistance Range:
- Typically, resistors are available in the range of 1Ω to 1MΩ.
- Some applications may require resistors with values below 1Ω or above 1MΩ.
