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

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 ...

Electricity doesn’t just flow freely in every direction—it needs control. That control comes from a tiny but powerful ...

For electricity to flow, everything needs to be connected in a big ring. It’s called a circuit. For example, the lights in most houses and flats are part of a circuit controlled by the consumer unit, ...

The transistor is probably the most important invention in electronic engineering and the basis for nearly all integrated circuits (ICs). The transistor is a three-terminal electronic device that can ...

Troubleshooting refrigeration equipment often requires measuring various electrical properties such as voltages, current flows, and resistances. Understanding these basic electrical fundamentals and ...

A parallel circuit is way of connecting components on separate branches, so the current can take different routes around the circuit. The current is different in different parts of a parallel circuit.

If you got your start in electronics sometime after 1980 your first project might well have been to light up an LED. Microcontroller projects often light up an LED, too, and a blinking LED is ...

There are many cases where a power supply needs an internal current-limiter function, usually built using a current sensor, a control circuit, and a pass transistor. The current sensor itself can be a ...

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 ...
