Basic Electronic Components Used in Circuits

May 13, 2013 By Øyvind Nydal Dahl 179 Comments

Some basic electronic components drawn as cartoons

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.

FREE Bonus: Download Basic Electronic Components [PDF] – a mini eBook with examples that will teach you how the basic components of electronics work.

The Most Common Basic Electronic Components

These are the most common components:

  • Resistors
  • Capacitors
  • LEDs
  • Transistors
  • Inductors
  • Integrated Circuits

Resistor

A Through-Hole Resistor
Find the resistor symbol in the schematic symbols overview.

I didn’t understand the resistor in the beginning.

It didn’t seem to do anything! It was just there, consuming power. But with time, I learned that the resistor is actually extremely useful.

You’ll see resistors everywhere. 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.

Some basic electronics components: LED in series with a battery and a resistor

How?

By using Ohm’s law.

Let’s say you have a 9V battery and you want to turn on a Light-Emitting Diode (LED).

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 current limiting resistor.

Capacitor

Electrolytic capacitor
Find the capacitor symbol in the schematic symbols overview.

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.

For example to blink a light.

It’s commonly used for removing noise, or making the supply voltage of a circuit more stable.

Read more about the capacitor in this article: How Does A Capacitor Work?

There are many capacitor types. Most commonly, we divide them into polarized and non-polarized capacitors.

Light Emitting Diode (LED)

leds-in-a-pile
Find the LED symbol in the schematic symbols overview.

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 different types of LEDs.

A very common circuit to build as a beginner is the blinking light circuit.

Transistor

Two transistors in a circuit
Find the transistor symbol in the schematic symbols overview.

This is probably the hardest of the basic electronic components to understand.

But don’t worry, it’s not that hard.

A simple way is to look at the transistor as a switch controlled by an electrical signal.

If you put about 0.7 volts between the base and the emitter, you turn it on.

Note that this is true for NPN transistors. There are also other types, but worry about these later.

But, instead of having just two states (ON or OFF), it can also be “a bit on” by controlling the current that goes through its base.

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 amplifiers.

Explanation of how a transistor works

I’ve previously made a video on how transistors work.

Inductor

A homemade inductor
Find the inductor symbol in the schematic symbols overview.

Inductors are a bit weird.

It’s just a coil of wire – and you can make one yourself by making some loops out of a wire.

Sometimes they’re wound around a metal core of some sort.

They are often used to make radio oscillators, more efficient power supplies, and filters.

It’s not that often that I used one actually, but in my article What is an inductor? you can see how it works with some nice animations.

Integrated Circuit

Integrated circuit - one of the basic electronic components
Find the integrated circuit symbol in the schematic symbols overview.

An Integrated Circuit (IC) consists of many basic electronic components.

It’s nothing mysterious or magical.

It’s just an electronic circuit that has been shrunk to fit inside a chip.

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 datasheet.

What to do next?

Now, you know a bit about the basic electronic components.

But don’t just read about it – take action and start building electronics:

      If it is not complete, that is you don’t have a closed loop, then no current will flow and nothing will happen.

    So a transistor is like a switch that i can put in halfway down a power wire for like an LED and turn it on from somewhere else with a switch that powers the transistor. And then transistor will turn the LED on and off by controlling the power flow into it. Have i got that right?

    You did a really good job explaining the parts of a circuit. I’m sure that I read similar books to you in the beginning and it always took me reading the information two or three times before it really sank in. I just wanted to learn how circuit boards worked and it didn’t take long to get in over my head. 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.

      I have made some DIYs before and last time it was a speaker with the led light. You should try more, it was not very difficult as long as you have the right introduction and all tools on hand.

    Dear, i am confused about what you have written about resistor. I think when we connect a resistor in series with the led the current will remain same because in series current remain same but voltage divides so i think in this case the resistor act as a voltage limiting resistor.

      Hi,

      A LED without the resistor in series will have a lot of current flowing through it. Let’s say 100 mA for the sake of the explanation. But if you add a 330 Ohm resistor in series with it, the current is 21mA.

      The current is the same in the LED and in the resistor yes, but if you compare the circuit with and without a resistor – you’ll see that a resistor in series limits the current.

    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? I actually have like 5 fans and they all have the same black box and all 5 don’t work. Could you help me understand what these boxes are all about? Some yahoo told me that they are capacitors, and that they help the fan start spinning, but if thats the case, why when I help the fan start spinning with my hand, they still don’t work. 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…..I’m just stupid. Love the site and thank you from the bottom of my heart, nobody else is trying to teach people about this stuff in a way that’s understandable to the non electrician .
    Sincerely, skin

      I’ve never really looked into the components of a fan, but yes, sounds very much like a capacitor you are seeing. And when googling, I found this answer that explains how it works:

    So I got into circuits because I was wanting to make more advanced Energy Constructs and “functional sigils” for Magick. funny how many of these symbols go back to Norse Galdrstafr and carry similar meanings, for instance the symbol for antennae and aerial antennae are the same as in bindrunes, and is for sending and receiving information/energy, capacitors have same symbols, also the symbol for allowing energy to pass but not back flow are all the same… so I have come to the conclusion that the 1st Master Electrician was also a Master Magickian.
