About this app
The electrical wiring in your home that keeps your laptop, phone charger, and lesser tools such as refrigerators and stoves humming along consists of a number of interconnected electrical circuits. These are connected to whatever power source supplies electricity to your home.The purpose of circuits is to get electricity and its considerable energy potential exactly where it needs to go, and to contain the potentially harmful effects of electricity in the process.
What's going on inside all those wires, which themselves are mostly out of your sight? To start with the basics, free electrons will move in the presence of an electric field, for physical reasons that will be described later. If they are given a closed-loop path in which to flow, an electrical circuit can be created.
A simple circuit consists only of a source of voltage (electrical potential difference); a medium through which electrons can flow, usually a wire; and some source of electrical resistance in the circuit. Most real-world examples are far more complex, however, and multiple types of electrical circuits exist, all of which are vital to the efficient flow of electricity.
