In normal conversation, power is often interchanged with a lot of similar but actually different words - energy is a big one. Power is the amount of energy that is expended ...

I have to admit, I’m biased. I think LEDs are awesome. But, really, the reason I’m biased and love them so much is because they’re just so cool. I’ve found that as I replaced ...

Every circuit has a power source, or else it won’t do much. While the actual power source can vary wildly, they all fit under the two general titles of “voltage source” or ...

Potentiometers. Pots. Trimmers. Rheostats. If you’ve done very much with electronics, you’ve heard at least a couple of these words. Maybe you’ve heard them interchangeably and ...

If we recall some basic topics in chemistry, we’ll remember that all atoms consist of neutrons, protons, and electrons, except for a normal hydrogen atom which doesn’t have a ...

One would think that, if you need a specific resistance, you would find a resistor of that resistance and you’d never have to worry about putting multiple resistors together. ...

Before semiconductor devices existed, vacuum tubes were the only devices available for signal amplification, switching, and other applications. Though vacuum tubes are ...

Multimeters are used by anyone who deals with electricity. They’re very versatile and can be used to characterize an embedded system or troubleshoot a non-functioning lightbulb ...

We are going to have a quick discussion of the two classifications of semiconductors, which will help us understand the basics of semiconductors better.

With the amount of fully functional development boards out there, it’s possible that you won’t use a breadboard very often. However, if you spend enough time in electronics, ...

Despite the fact that there are many, many buttons on an oscilloscope, if you keep things simple and ignore what you don’t need, they’re not too bad to use. Let’s go over what ...

There are two different ways to look at phases. First, it’s when voltages are out of phase from each other, such as with 3 phase power, and second, when voltage is out of phase ...

Let’s talk about DC versus AC electricity, the difference between them, and some pros and cons of each. DC stands for direct current, which is easy to remember that the current ...

We’d like to delve more into electrons and how they are related to electricity. First, perhaps the most important thing you should understand about electrons is that they hate ...

Understanding the basics of what electricity is can really help anybody learning about electronics, circuit design, power engineering, and so on. So, let’s start with a little ...
