  • A diode is a component that only allows current to flow through it in one direction.
Rectifiers

Rectifiers

  • A rectifier is a component that turns an alternating current (repeatedly changes direction) into a direct current (one direction).
  • Diodes act as rectifiers as they diode block the alternating current when it changes direction.

Test yourself on Diodes

  • Which of these can a diode not do?
