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.
