Principle

Investigate the electric field, which is created by applying a voltage to two parallel rod electrodes.

Benefits


No electrolyte required

Direct measurement of potential with high resistance voltmeter

Measuring points can be transferred (pressed through) onto a sheet of white paper during measurement


Tasks


Measure the distribution of the electric potential between the two electrodes and identify lines of equal potential (equipotential lines).

Determine the electric field pattern.


What you can learn about

With this experiment the students will learn about the concepts of "equipotential lines" and "field lines", using the example of a homogeneous electric field. At first, the students will locate five equipotential lines of the electric field. They then will elaborate the corresponding field line distribution in the evaluation part.
