In our discussion with half-wave rectifiers, we’ve learned that half-wave rectifiers only rectify the half-cycle of the AC input. Though they can be used in some applications, ...

Welcome to this tutorial about full-wave rectifiers. We've done a tutorial on half-wave rectifiers and now this is an opportunity to see why full-wave rectifiers are even ...

If you get a transformer that has a dual primary side and a dual secondary side, there may be some questions about how to connect the leads so that the transformer is setup ...

Hello again! This time we will try to establish the connection between the PIC10F200 microcontroller and a typical personal computer. Obviously, we can’t connect it to the PC ...

We use a lot of different components in our electronics devices but diodes are usually the first non-linear component people use in a circuit. Whether it’s because they’re ...

Hi there! After the last two tutorials, we are confident about dealing with buttons. Today, we’ll expand this knowledge and learn how to check the state of the several buttons ...

In our discussions about diodes, we have learned that a PN junction is a boundary formed between a P-type and N-type semiconductor when they are combined. When a PN junction is ...

Ho! Ho! Ho! Christmas is coming soon, so it’s time for some magic. And I’ll show you some real magic today. As we all want to feel relaxed before the Christmas holidays, I ...

Have you ever wondered why we operate a Zener in reverse bias unlike normal diodes that are operated in forward bias? This is because Zener diodes are meant to ‘break down’. ...

Hi again! After the meaty last tutorial, I think it would be good to rest a bit and consider something relatively easy and short. Also, I haven’t provided a homework solution ...

Hi again! This time we’ll put the LEDs aside and try something new. We will play music using a buzzer. Interestingly, some of the basic concepts are the same as with the LEDs ...

Hi there and welcome back! In tutorial 6, we made an LED blink and this time, we’re going to control the LED again but, unlike last time, we will not just blink the LED but ...

A transistor is an electronic device that can be used as an amplifier or as an electronic switch. Its ability to amplify a signal or to switch high power loads using a small ...

Welcome to the second part of asking engineering jobs, where we talk more about the jobs and career opportunities for electrical engineers. With that, let's get back into it.

Welcome to Ask an Engineer where we are going to talk about jobs, this time. Careers, electrical engineering jobs and careers, things like that. And so in this, basically, we ...
