Physics studies the fundamental relationships of nature.
It forms the basis for all other technical topics
such as electronics and chemistry.
Here you will find the key physical topics illustrated by experiments.
You want to start with the experiments? Take first some time for your lab equipment. What you need and other important information, safety instructions, etc. can be found here.
The electricity describes phenomena related to electric charge. It explains electric current and voltage, but also electrical resistance, as well as electric and magnetic fields.
Semiconductors can be conductors or insulators. This depends on the internal structure of a semiconductor, but also on the external influences. This results in interesting physical properties and applications.
