NOTE

RESISTORS

A resistor is an electronic component that resists the flow of electric current. It's commonly used to control the amount of current in a circuit, regulate voltage levels, and divide voltage.

Practical applications of resistors

  1. Voltage division: Used in potential dividers to create reference voltages or control the voltage level in a circuit.
  2. Current limiting: Protects components from excessive current by limiting the flow.
  3. Signal conditioning: Adjusts signal levels for compatibility between different parts of a circuit.
  4. Temperature sensing: Changes in resistance with temperature can be used in sensors.
  5. Filtering: Used in conjunction with capacitors to create low-pass, high-pass, or band-pass filters.
  6. Timing circuits: Used in combination with capacitors in RC circuits for timing functions.
  7. LED protection: Limits current to LEDs to prevent damage from excessive current flow.
  8. Pull-up/pull-down resistors: Used to ensure a known state in digital circuits.
  9. Load balancing: Used to balance loads in parallel circuits.
  10. Impedance matching: Matches the impedance of different parts of a circuit for maximum power transfer.
