## Introduction to Resistors

The most important component to understand in electronics is the resistor. This is because we use the resistor to model much more complex systems. If you understand how to do "resistor math" then solving complex systems becomes much easier. Lets review the basics. They come in various values that are expressed in Ohms. You can determine their value by using […]

## Begining Circuit Analysis and Ohms Law

Circuit analysis is the process of looking at a circuit and figuring out what it does. For simple circuits this is pretty easy. For complex circuits it can be amazingly hard, even for pros. This guide will get you started with circuit analysis. Lets start with a simple circuit and figure out what it does. If you have been reading […]

## What Is A Circuit

A very common term in electronics is the word circuit. In general, you will hear the word used to describe what a schematic shows. Most projects are a circuit and most schematics are a circuit. The literal definition of a circuit comes from "circle", and is used to refer to the path that electricity flows in a project. Lets look […]

## Common Schematic Symbols

There are literally 1000’s of schematic symbols out there, and you should never expect to know them all. There are about 10 that you should memorize, and the rest you can look up. Here we will show you some common schematic symbols and give a brief description of them. Some of them you may already know. We’ll start with common […]

When we talk about electronics it is sometimes easier to use a picture to describe what we are talking about. Those pictures are called a schematic. A schematic is a picture representation of what we are talking about in electronics. They may look hard to read at first, but in time you’ll find that they are usually easy to read. […]
