FET constant current sources use JFETs and MOSFETs to deliver a load current, which remains constant despite changes in load resistance or supply voltage. A FET constant current source is a type of ...

Q. The Code prohibits "objectionable currents;" what is this, what are some examples, and how can it be prevented? A. Section 250.6 of the 2011 NEC addresses objectionable current. First of all, the ...

For some strange reason, many rodders exhibit a great deal of resistance when it comes to dealing with electrical systems and wiring fundamentals. They feel there's something inherently mysterious ...

Current sources are widely used in industrial control systems to transport analog process signals over long distances, but they are less widely used than voltage sources. This post loosely reviews the ...

The film explains how electric current is generated at power plants and delivered to homes through wires. It describes the concept of electric circuits, including closed and open circuits, and the ...

Download this article in PDF format. It’s now common to see circuit boards that carry hundreds of amps, especially in intensive data-processing applications, electric vehicles, and ac distribution.

If you are an EE you definitely know the answer to this, or at least you think you do. If you said positive to negative, you are wrong. Then you remember that current flow is a charge of electrons ...

Introduction Electricity powers many of the devices you use every day. Those devices are made up of circuits, ranging from very simple (such as a lamp with a single lightbulb) to very complex (such as ...

Testing for failure with a multimeter is only partially effective, whereas a dedicated optocoupler testing circuit provides clear results in just seconds. For related tutorials and step-by-step build ...

This is the first of a two-part series on the processes used to find the short circuit current duties of circuit breakers and fuses. In Part 1, we’ll use a simplified power system to illustrate the ...
