==Key Stage 4==
===Meaning===
[[File:DiodeSymbol.png|right|300px|thumb|The symbol for a '''diode'''.]]
A '''diode''' is an [[Electrical Component|electrical component]] which only allows [[electricity]] through in one direction.
===About Diodes===
: [[Diode]]s have a low [[Electrical Resistance|resistance]] in one direction but a very high [[Electrical Resistance|resistance]] in the reverse direction.
: [[Diode]]s can be used to change an [[Alternating Current|alternating current]] into a [[Direct Current|direct current]].
