Having some knowledge about basic electronics circuits is a practical choice. Most of the devices and equipments we use today uses electricity for power.If you want to know how to replace a fuse or repair a simple device, then knowledge of basic electronics circuits is essential. On top of that,you can fix simple problems without needing the assistance of an electrician; thus, you can apply wat you know about basic electronics circuits. In the same manner, you save money by doing it yourself.
To be able to have a good grasp of basic electronic circuits, you need to know some terms and concepts. You must realize that dealing with electricity also poses some risks on your part. For you to be effective and safe while fixing stuff, read the following to serve as a guide:
Circuits - This concept has similarity to a circle in terms of flow of energy. The circuit is the path where electrons pass through coming from one terminal and reaching another terminal. There are only two terminals: positive or negative. The flow happens using a single direction- negative to positive. In all cases, positive electrons always attract negative electrons; thus, opposites attract.
Conductor - The freeway, made up of a material that electrons can pass through. In most cases, copper is used due to high conductivity. Transmission between terminals is enhanced due to high-conductivity.
Insulator- It simply insulates the conductor by wrapping around it;also, it is commonly made up of rubber material.Definitely, you wouldn't want to hold or even touch live wires. Insulation protects the conductor.
Now, you must know that there are two types of circuits: series or parallel.The difference between series and parallel circuits is direction of flow; a series flows only one-way. Perhaps, you observed that some light bulbs don't work when one light bulb blows off. This is an example of series circuit. On the other hand, parallel circuits have one or two more paths available for electricity. Because of this, your Christmas light bulbs keep on twinkling even if some of the bulbs are busted. A basic series circuit is often used for wiring the lights inside homes. Almost all consumer appliances are built with parallel circuits because it's more stable. However, if the problem can't be fixed by basic measures, ask help from an expert.
