Introduction In this installment we examine inductors (also called coils) and their behavior in DC circuits. We'll look at what they are, what they do, and how they respond in both steady state and transient conditions (i.e. a state change). In addition to the theory, we'll spend some time in the lab looking at real-world … Continue reading Beginner’s Corner: Inductors in DC Circuits →

Welcome! In this installment we'll cover Zener Diodes including some practical applications. We'll also learn that although Zener Diodes make great voltage references, in most applications they are a poor choice for voltage regulators. https://youtu.be/wjRmVucFigM If you enjoyed that then please subscribe, like and share.

In this installment we learn how to use MOSFETs to switch large amounts of current. We'll look at some basic MOSFET parameters as well as a few sample circuits both in theory and in the lab. https://youtu.be/0hKlFBsVJpE I hope you enjoyed that and learned a little about MOSFETs. If you did, then please give it … Continue reading Beginner’s Corner: MOSFET Switches →

In this installment we start a discussion of semiconductor components, specifically diodes, and even more specifically rectifier type diodes. https://youtu.be/qL5iF2ox_Wo If you enjoyed that, and learned something, consider subscribing and sharing. Until next time. Cheers. Dominick

Welcome! In the last installment on capacitors, we discussed what capacitors are, what they do, and the different types of capacitors available. At the end of the lesson we took a very brief look at how capacitors charge and discharge. In this installment, we’ll take a much deeper look at how capacitors behave in DC … Continue reading Capacitors in DC Circuits →

Welcome! This is the first of a three part series on capacitors. In this installment we’ll cover what capacitors are, what they do, and the different types of available  capacitors. Part 2  discusses capacitors in DC circuits, including both steady state and transient response. In Part 3 we take a limited look at capacitors in … Continue reading Capacitor Basics →

In this 4th and final installment on resistors in DC circuits we complete our discussion of the most commonly used electronic component, the resistor, with a look at resistor-based sensors. At the end of the lesson we,ll take a look at some resistor-based sensors in the lab. The video is at the end of this … Continue reading Resistor-Based Sensors →

Our last two lessons covered fixed-value resistors. In this lesson we'll cover potentiometers - devices whose resistance varies when you turn or slide a knob. At the end of the lesson we'll head into the lab and demonstrate what we learned (see the video at the end of this post) and that the measured results … Continue reading Potentiometers – Variable Resistors →

In the last lesson we learned about resistors; what they are, what they do, and their basic characteristics such as tolerance, power rating, and value. In this lesson we'll take that a step further and look at how resistors combine in series and parallel, learn to analyze DC circuits that contain resistors using Ohm's and … Continue reading Resistor Circuits →
