A resistor is an electrical component that limits or regulates the flow of electrical current in an electronic circuit.

About them

  • The propose of a resistor an amount of electrical resistance in a circuit.
  • When a resistor conducts an electric current, it's temperature increases.
  • Resistors can also be used to provide a specific voltage for an active device such as a transistor.
