Kit for general electricity

The kit is composed of a set of components and devices that allow a practical demonstration of the most important laws of electricity and electromagnetism.

All the components are mounted on metal or plastic bases complete with terminals for an easy connection of the test circuits through multiple jack cables.

The kit is supplied with a manual that outlines the different subjects of the practical exercises in a simple and progressive way. It is to be underlined the importance of the suggested method, which is based on the direct observation and quantification of the phenomena to highlight the fundamental scientific laws.

Due to the simplicity of its components and to the guided testing procedures contained in the manual, this kit is suitable for courses both in electrophysics and electrical engineering. The tests can be carried out by students under full safety conditions.
