Dielectrical constant / relative permittivity

  • #1
Hi!

Im woundering if the relative permittivity in a capacitor is dependent on
the level of charge in the capacitor?

The charge on the capacitor affects the E field through the dielectric. In an ideal capacitor the permittivity is independent of field. Real devices have some degree on nonlinearity (eg at high voltages they will simply break down).
