In the Feb. 22 issue of RWEE, we asked: What is skin effect in alternating current and what is its relationship to current flow? a. Skin effect is the tendency of all current flow on printed circuit ...
The battery as we know it today was an invention of Italian chemist and physicist Alessandro Volta. He witnessed electricity splitting water into its constituent elements of oxygen and hydrogen and ...
The topic of motors and motor control techniques is wide and varied. Part one of this two-part article will cover the principles of alternating-current (AC) motor operation and control. Part two will ...
Mechanical relays, contactors, and switches control the flow of electricity by the mechanical action of two conducting elements. The physical contact of two conducting elements creates a path for ...
As power electronics switching techniques advance, there is an increased need to accurately measure current for feedback control and system monitoring. There are several methods to achieve this, and ...
Power relays are specifically designed to handle either AC or DC. It’s important to know the fundamental differences between them before building them into a system. Introduction to AC and DC Power ...
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 ...
