11.4. Electric field

electric field strength


= voltage in V




= thickness of the dielectric in m



charge

Q = I · t

[As]

capacity

[F]


Q = quantity of electricity in AS




C in F (1F = 1 AS/V)



equation of dimensioning


dielectric constant


relative dielectric constant

er: matter constant, relative to the vacuum


absolute dielectric constant


dielectric flux density

D = e · E
