This article begins a series of lectures on analogic electronics.
It assumes that the reader knows basics of electrical engineering and knows behaviors of electrical and electronical components like resistors, capacitors, inductors, diodes and transistors.
The course focuses Operational Amplifier and circuit configurations that use it.

One classical example to take confidence in electronic circuits is related to charging/discharging capacitors (symbol: C).
These components are able to catch electrical charges and to keep them for a long time; theoretically for an infinite one, but this is impossible, first of all because of Joule effect (heat dissipation to the ambient with slow progressive energy loosing).
