Ohm, Georg Simon
A German physicist. As a high school teacher, Ohm began his research with the recently invented electrochemical cell, invented by Italian Count Alessandro Volta. Using equipment of his own creation, Ohm determined that there is a direct proportionality between the potential difference (voltage) applied across a conductor and the resultant electric current. This relationship is now known as Ohm's law.

In electronics, an opto-isolator, also called an optocoupler, photocoupler, or optical isolator, is a component that transfers electrical signals between two isolated circuits by using light.

Ordinary trigger mode is a mode when a signal record happens only after the trigger event detection. Prior to the data recording the oscilloscope stays in the trigger event waiting mode.

A group of people and facilities with an arrangement of responsibilities, authorities, and relationships.
