relative permittivity
editOriginally proposed at Wikidata:Property proposal/Natural science
| Description | measure of capacitance that is encountered when forming an electric field in a particular medium expressed as a ratio relative to the permittivity of vacuum |
|---|---|
| Represents | relative permittivity (Q4027242) |
| Data type | Quantity |
| Template parameter | This proprety request is part of the project of creating an infobox for materials. |
| Domain | Physical property of material (Q214609). |
| Allowed values | Any number. Qualifiers : frequency (P2144) (mandatory), temperature (P2076) (mandatory), under pressure (P2077), determination method or standard (P459), microstructure (P5589), Work hardening strain, Heat treating |
| Allowed units | dimensionless |
| Example 1 | vacuum (Q11475) → 1 |
| Example 2 | air (Q7391292) → 1.00058986 ± 0.00000050 at frequency (P2144) → 0.9 MHz temperature (P2076) → 0°C, under pressure (P2077) → 1 bar |
| Example 3 | water (Q283) → 80 at frequency (P2144) → 1.77 MHz temperature (P2076) → 0°C, under pressure (P2077) → 1 bar |
