Principle

A uniform electric field E is produced between the charged plates of a plate capacitor. The strength of the field is determined with the electric field strength meter, as a function of the plate spacing d and the voltage U. The potential ø within the field is measured with a potential measuring probe.

Benefits

  • Loss-less measurement of electric field strength
  • High-sensitive electric field meter also suitable for electrostatic measurement of voltages

Tasks

  1. The relationship between voltage and electric field strength is investigated, with constant plate spacing.
  2. The relationship between electric field strength and plate spacing is investigated, with constant voltage.
  3. In the plate capacitor, the potential is measured with a probe, as a function of position.
