Electronics concerns sceintific and technological developments for the production, study and eploitation of  electro-magnetic phenomenums. As previously noticed, telectrical properties of materials are due to the way electrons move inside materials and how we can control and exploit a flow of such electrical energy.

Electronics differs from electricity as it does not deal with high power and more with direct than alternative current. The science is the same, but applications and danger differ considerably, and you should never use electronic components with high electric power but only with the appropriate power source.

We provide here a basic review of the educational knowledge provided to safely produce basic electronic circuits using the appropriate materials and the mostly used componenents.
