Most circuits that require current loss detection use expensive isolation amplifiers. This circuit solves that problem with a simple and low-cost method to detect current loss of 4-20 mA.

The direction of conventional current is the direction marked on all circuit diagrams. The symbol for electric current is I.

Here, you can construct simple circuits, apply essential laws and electrical relationships, and solve problems, all in a safe, digital environment.

The difference between static discharge and continuous current is explained. Introduction to Electric Current: The difference between static discharge and continuous current is explained. Sources ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

A battery maintains a nearly constant change in electric potential across its terminals. When a complete circuit is connected from one terminal to the other, there is an electric current.
