Wikipedia:WikiProject Electronics/Standard symbols

Reference should be made to codes and standards. For example, IEC 60027, and Letter Symbols in Electrical Technology.

Here are tables of widely accepted symbols. They are meant to be a guideline: Using the same symbols for the same things in different articles will increase their consistency, making them easier to understand and to improve. If you are looking for the symbol for something that is not on the list, just check whether a particular symbol has been already chosen, and create your own. If anybody will disagree with it, discuss it on the talk page.

It is certainly not an exhaustive list, nor is it in any particular order.
