Introduction to Electricity

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 ...

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 ...

There are two varieties of electric current that flows through our electrical or electronic devices — AC and DC. In this tutorial, we are going to discuss DC (Direct Current) ...

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 ...

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. The ...

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 ...

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 ...

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 over a ...

Resistors are the most common electronics component in the world. They’re used in many forms of circuits as voltage dividers, to keep current levels under control with things like ...

Before we can get too deep into voltage dividers, it is essential to have a good understanding of what happens with Parallel and Series Resistors. Once you understand how a ...
