Georg Simon Ohm, a German physicist, demonstrated proportionality between current and voltage, thus defining resistance (this rule was named after him as Ohm's law).

From this moment it starts a diary on electronics design, the idea has been born from all the FORUMS that deal several arguments, all related to specific fields, for example Microchip or Telit, but nobody, no FORUM, doesn't follow, obviously, the general activities of an electronics designer! And it's obvious for the companies, but for the designers is without doubt a deficiency!!
