Resistor

A resistor is a passive two-terminal electrical component that implements electrical Resistance.

Definition

Resistors limit the flow of electric Current in a circuit. They are measured in ohms (Ω) and come in various types and Power ratings.

Key Points

  • Most common passive component
  • Used for Current limiting, Voltage division, pull-up/pull-down
  • Power rating determines maximum Current
