7. Electrical symbols Fuse A diode or a light-emitting diode (LED)
Wire of low melting point that breaks a circuit if the current exceeds a certain value.
Ordinary diode
LED
A diode allows the current to flow in one direction but not in the opposite direction.
LED also glows if it is conducting current.
