When you need a multimeter for testing electrical equipment around the home, it's vital to know what all those symbols around the dial mean.

Negative differential resistance, sometimes called negative dynamic resistance (NDR), occurs when an increase in voltage ...

In this article we talk about resistors in parallel, the equivalent resistance and the current divider rule for parallel connection of resistors. Let’s consider this circuit: In circuit 1 we have two ...

Designers often use mathematical models to predict how mechanical and electrical systems will behave. The details expressed by these models, like significant Designers often use mathematical models to ...

An inductor's apparent inductance varies with the measurement method and frequency. William Hays, BH Electronics, Inc., Marshall, Minn. Inductors range from RF coils used in communications through ...

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 ...
