Some facts#
- Simply speaking permittivity tells us how easily electric phenomena propagates withing given medium.
- Permittivity is usually denoted by the Greek letter epsilon: .
- Electrical permittivity can be defined as the ratio of the electric field induction to the field strength:
- The medium with the lowest permittivity is vacuum:
- Basic permittivity unit in SI system is farad per meter:
- Two electrical charges , isolated by medium with permittivity , act on themselves with force:
where:
- - force with which and charges interact,
- - value of first charge,
- - value of second charge,
- - permittivity of medium between charges,
- - distance beetween charges.
- - force with which and charges interact,
- Relative permittivity is sometimes called dielectric constant.
- Relative permittivity tells us how many times the permittivity of a given medium is greater than the permittivity of vacuum:
where:
- - relative permittivity of medium,
- - absolute permittivity of medium,
- - permittivity of vacuum.
- - relative permittivity of medium,
- Medium permittivity depends on temperature and pressure. Values given in this calculator have been measured at the pressure of 1013,25 hPa and temperature of 20 °C.
