diodes

Current's one-way gates

A diode is an electronic component that allows current to flow in only one direction, acting as a one-way valve for electricity.

Diodes appear in countless circuits—converting alternating current to direct current, protecting against reverse voltage, and emitting light (LEDs).

The bridge rectifier uses four diodes to convert AC to DC.
