Dielectric constant of different materials

Product No: P2420600

Principle

The electric constant is determined by measuring the charge of a plate capacitor to which a voltage is applied. The dielectric constant is determined in the same way, with plastic or glass filling the space between the plates.

Tasks

The relation between charge Q and voltage U is to be measured using a plate capacitor.
The electric constant is to be determined from the relation measured under point 1.
The charge of a plate capacitor is to be measured as a function of the inverse of the distance between the plates, under constant voltage.
The relation between charge Q and voltage U is to be measured by means of a plate capacitor, between the plates of which different solid dielectric media are introduced. The corresponding dielectric constants are determined by comparison with measurements performed with air between the capacitor plates.
