Principle
Investigate the electric field, which is created by applying a voltage to two circular 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
Determine the equipotential lines of the electric field between the two electrodes and derive the electric field pattern.
What you can learn about
With this experiment the students will investigate the electric field between two circular electrodes. This field corresponds to the attractive field between two point charges. It also referred to as a static dipole field and serves as an example of an inhomogeneous field.
