The kit contains about 15 different components with which a number of experiments can be performed. The components are designed so that students can quickly and easily perform their laboratory work. The kit can show how the following forms of energy are generated:

Supplier: MOLLER THERM

Radiometer according to Crookés. Consists of a glass container on foot with low air pressure and needle-bearing spinner with four vertical mica discs. The discs are black on one side and shiny on the other. The discs thus absorb radiation differently. The higher temperature of the dark side means that the air molecules get greater kinetic energy in collision with the dark side of the discs than with their shiny side. The result is that the spinner starts to rotate.

Supplier: 3B Scientific

Highly evacuated electron tube for determining the wavelength of electrons as a function of the anode voltage from the radii of the diffraction rings and the distance between the lattice planes of graphite (Debye-Scherrer-diffraction) and rendered visible on a fluorescent screen. Also intended for determining the wavelengths of monochromatic radiation at different anode voltages from the radii of the diffraction rings and the lattice plane spacing of graphite, as well as confirming de Broglie’s hypothesis.

Supplier: CORNELSEN EXPERIMENTA

Apparatus for examining the conversion from electrical energy to light and heat energy. Consists of a plastic container, lid with light bulb (6 V / 5 A) in base and a resistor. The container is filled with water and the temperature change is measured. Equipped with connections for 4 mm banana plug.

The kit contains components for basic laboratory work with solar cells. The components are simply designed and the students quickly build their experimental setups. With the rate, e.g. the following are studied.

Supplier: CORNELSEN EXPERIMENTA

72 series-connected semiconductor elements, mounted between two ceramic plates which in turn are attached to heat-conducting metal. If the metals are exposed to different temperatures, a voltage arises, sufficient to drive, for example, a slightly rotating motor. The thermogenerator can also be run in the other direction, ie. a voltage is connected and a temperature difference is obtained across the metal legs.

Supplier: GR NNA PLASTEMBALLAGE AB

Semiconductor type nonlinear resistors with large negative temperature coefficient (NTC resistors). Used for studies of temperature dependence of resistances, such as temperature sensors, current limiters, etc. Of standardized disc type with connecting wires.

Supplier: 3B Scientific

Highly evacuated electron tube with focusing electron gun and fluorescent screen (90×60 mm) inclined relative to the beam axis, so that the path of the beam can be seen and the effects of electric and magnetic fields can be studied. The electron beam can be deflected electrically in the electric field of the built-in plate capacitor, and magnetically by using an optional Helmholtz coil pair D. By adjusting the electric field so that it cancels the magnetic deflection, it is possible to determine the specific charge e/m and the velocity of the electrons.

Supplier: CORNELSEN EXPERIMENTA
