In this overview the pages with the basic concepts in electrical engineering are shown. This includes: the basic electronics page on which the basics of electricity and the concepts of voltage, current and resistance are explained. Ohm's Law can be used to determine and explain the relationships between these three quantities. The other pages also relate to basic electronics, but more with an application, such as series, parallel and combined resistors, of which the replacement resistance, partial currents and voltage drop are described. The pages in this overview provide the reader/technician with the basic knowledge to get started with the electronic components and diagnosis.
