Editing Diode (section)

===Graphic symbols===
{{Main article|Electronic symbol}}

The symbol used to represent a particular type of diode in a [[circuit diagram]] conveys the general electrical function to the reader. There are alternative symbols for some types of diodes, though the differences are minor. The triangle in the symbols points to the forward direction, i.e. in the direction of [[conventional current]] flow.
