Error: "polarity" must be defined.
This template generates a polarity symbol, indicating that a device requires a direct current power supply with either a positive- (
) or negative-center (
) coaxial power connector (barrel plug). Alternatively, the template can be used to generate a fullwidth tilde (～), a symbol which indicates alternating current, which some devices require from their barrel-plug power supply.
This template is especially useful for infoboxes such as {{Infobox computing device}}, which have a "power" parameter for giving power consumption specifications. A reliable source backing up the polarity information is required.
Note: Please check to see if the image generated corresponds to the symbol on the device the article is about!
Usage edit
This template can used either with named parameters, as in...:
- {{polarity|polarity=positive|size=40}}
...or without:
- {{polarity|positive|40}}
TemplateData edit
TemplateData for Polarity
A template for adding a electrical polarity symbol, indicating that a device requires a power supply with either a DC positive-center, DC negative-center, or alternating current (AC) ''barrel plug'' connector.
| Parameter | Description | Type | Status | |
|---|---|---|---|---|
| Polarity | polarity 1 | The polarity of the coaxial power connector/''barrel plug'' connector that the device requires.
| String | required |
| Size | size 2 | The size in height of the positive- or negative-center symbol to be displayed, in px. Defaults to 14 (px). Any other measurement (e.g. mm, em, in) is ignored.
| String | optional |
