Applying a variable voltage source, you can charge metal balls of different sizes and a spherical capacitor. A measuring amplifier is used to determine the induced […]
A test capacitor is charged through an electrical heater and the current flowing in the circuit is calculated based on the time; it’s also assess the […]

The behaviour of a coil in a DC circuit changes as soon as the DC supply is turned on or off.
Conductive spheres of different diameter Are electrically charged: a meter of the electric field and of a voltage probe allow you determining the static potential and […]
Using a torsion spring in this experiment enables to measure the Coulomb force being generated between two charged balls. The equipment consists of a rotating body […]
The relationship between capacitance C, charge Q and voltage V is described by ratio C=Q/V. The capacitance of a parallel plate capacitor depends on distance “d” […]
Kit for the recording of equipotential lines of electric fields. By electrodes of different shapes, the equipotential lines of a plate capacitor, an induced surface charge […]
A very simple test demonstrates that if a plastic rod is rubbed with a cloth, it will be able to attract small pieces of paper. This […]
This type of generator consists of a belt of insulating material stretched between two pulleys and kept in rotation by a motor.
