An electric current can be induced in in a coil of wire by moving a magnet in and out of the coil. AC generators are used in the generation of electricity and in their simplest form consist of a coil ...

The harnessing of electricity has played a pivotal role in human history and has exponentially expedited our growth as a species. Since becoming a household commodity in the late 19th century, ...

Poor Topsy. Thomas Edison killed the ex-circus elephant, electrocuting the animal to demonstrate how dangerous alternating current was. Edison even described electrocution as being “Westinghoused,” ...

A current transformer (CT) is a simple, practical and inexpensive means of detecting the presence of AC current. Detecting load current rather than applied voltage is a superior method of determining ...

We explain the difference between alternating current (AC) and direct current (DC) electricity. How do they affect EV ...

I finally did it. After years of wanting one (and pushing off projects because I didn’t have one) I finally bought an oscilloscope. Over the years I read and watched a ton of content about how to use ...

Alternating current (ac) or direct current (dc) circuits are capable of carrying very different currents, as illustrated by the ratings on the switch in Figure 1. This is why it’s so important for ...

Craig has worked in automotive media for nearly 20 years, producing content for publications ranging from Autoline and AutoGuide to Roadshow by CNET and EV Pulse. Aside from writing, he’s also ...

Any electrical motor, from an idealized viewpoint, consists of two sets of magnets—one set stationary, one set free to move—placed in special geometric relation to one another. For most practical ...
