The vast majority of bearing failures in electric motors and electric motor-driven equipment are due to mechanical and thermal causes. However, currents that flow through induction motor bearings can ...

Scientists have discovered a new material that absorbs visible light to generate electricity. This material might be useful for splitting water to produce a combustible fuel, hydrogen. Mined to make ...

This video explains how diodes function as directional components in electronic circuits. Diodes allow current to flow in ...

Physicists have made the first definitive measurements of "persistent current," a small but perpetual electric current that flows naturally through tiny rings of metal wire even without an external ...

A Japanese research group has discovered that a coffee compound can actually increase the efficiency of current flow by up to 100 times. Suddenly, spilling coffee on your keyboard might not be a bad ...

THE winds of the Oklahoma panhandle have a bad reputation. In the 1930s they whipped its over-tilled topsoil up into the billowing black blizzards of the Dust Bowl. The winds drove people, Steinbeck’s ...

Measuring the electrical resistance (ohms) of motors, compressors, and other electrical devices in HVAC systems may seem straightforward. But when the measurements of zero (0) or “OL” (overload) come ...
