I learned about the basic electronic components by going to the library and reading books. I was just starting out. And I felt like a lot of the books explained everything in a difficult way. In this article, I will give you a simple overview, with an explanation of the basic electronic components — what they are and what they do. It was just there, consuming power. But with time, I learned that the resistor is actually extremely useful. And as the name suggests, they resist the current. But you are probably wondering: What do I use it for? You use the resistor to control the voltages and the currents in your circuit. If you connect the battery directly to the LED, LOTS of current will flow through the LED! Much more that the LED can handle. So the LED will become very hot and burn out after a short amount of time. But — if you put a resistor in series with the LED, you can control how much current is going through the LED. In this case we call it a. Capacitor Find the capacitor symbol in the. You can think of a capacitor as a battery with very low capacity. You can charge and discharge it just like a battery. The capacitor is often used to introduce a time-delay in a circuit. Read more about the capacitor in this article: There are many. Most commonly, we divide them into polarized and non-polarized capacitors. Light Emitting Diode LED Find the LED symbol in the. A Light Emitting Diode — or LED for short — is a component that can give light. We use LEDs to give a visual feedback from our circuit. For example to show that the circuit has power. But, you can also used them to make cool light-show circuits. You see these components everywhere: In your laptop, on your mobile phone, on your camera, in your car +++ And you can find many. A very common circuit to build as a beginner is the. Transistor Find the transistor symbol in the. This is probably the hardest of the basic electronic components to understand. A simple way is to look at the transistor as a switch controlled by an electrical signal. If you put about 0. Note that this is true for NPN transistors. There are also other types, but worry about these later. A bit of current on the base produces a current of maybe 100 times more depending on the transistor through the Collector and Emitter. We can use this effect to build. Inductor Find the inductor symbol in the. Inductors are a bit weird. They are often used in filters. I rarely use one actually, but when I wrote that in my article a friend of mine reacted. See his response at the end of that article. Integrated Circuit Find the integrated circuit symbol in the. An consists of many basic electronic components. It could be an amplifier, it could be a microprocessor, it could be a USB to serial converter… It could be anything! To figure out what a specific IC does, you can read its. What to do next? Now, you know a bit about the basic electronic components. Do you understand the basic electronic components? Leave your comment or questions in the comment field below! If u tell me guide me or give me some tips That how can I troubleshoot the mother bird problem like no power , when connect the Adaptor to the laptop the goes off and how to trace out the some failure or short component in mother boards. Thanks Wow Im so greatful of you making it so under standing for us all GOD gave you this path to teach all your knowledge and for you to pass it on. I would say this is one of your paths GOD gave you to share GOD BLESS PS. I THANK YOU FOR MAKING MY BRAIN A LOT MORE KNOWLEDGED AND I WILL ACCEPT ALL THAT YOU CAN SHARE WAYNE WRONA You did a really good job explaining the parts of a circuit. Your explanation is much better for a beginner and I feel like the books would have made much more sense if I had read this first. Thank you for typing this up. I am trying to build a robot like baymax from Big Hero 6 by hand and looking up things used in computers, microchips, and codes that will help me in this case. I am willing to make it learn two languages and to do things like this, I need to know the basics and this article helps me understand what I need and how to use it. Hi, A LED without the resistor in series will have a lot of current flowing through it. But if you add a 330 Ohm resistor in series with it, the current is 21mA. Best, Oyvind Hey now, I have a box fan that stopped working. I tore it apart and found 1 electronic component, Besides the copper wire and the metal it was wrapped around. The component looks like a black box with a couple wires coming out of it. Can you tell me what this little black box is and what it does in relation to the workings of the fan? Could you help me understand what these boxes are all about? Whats up with that? By the way,your site is my goto electronics site when im confused. It helps me understand what the parts are and what they do, but my brain is confused when i look at all the parts, and i seem to instantly forget what they do, maybe some electric field fried my brain,but most likely…..
