Capacitors in DC Circuits
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
Lab Resistor Substitution Box – Part 5: Completion & Test
In this installment we complete the project and test it. See the video below. https://youtu.be/sp-BAHffKyM Well that's it for this project. Stay tuned for the next one. If you found it useful, then please like, share, and subscribe. Cheers Dominick
Lab Resistor Substitution Box – Part 4: Wiring the Switches
In this installment we'll wire up the six rotary switches. Each switch will be wired with 9 resistors so that we can select between 0 - 9 for each digit. Rather than try to describe the process with text, I'll let the video guide you through the wiring process. https://youtu.be/4H5iBpNmsZk Now just repeat that for … Continue reading Lab Resistor Substitution Box – Part 4: Wiring the Switches
Capacitor Basics
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
Lab Resistor Substitution Box – Part 3: Drilling the Front Panel
Look what I’ve got... The parts for our Resistor Substitution Box are in. I had two issues with the parts order, both related to the knobs. When the knob order arrived from Amazon, the envelope was empty. It was completely sealed all the way around, no rips or tears, but there was nothing in it. … Continue reading Lab Resistor Substitution Box – Part 3: Drilling the Front Panel
Resistor-Based Sensors
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
Lab Resistor Substitution Box – Part 2: Component Selection
Now that we have a completed design (see Lab Resistor Substitution Box - Part 1: Design), we need to select appropriate components so that we can begin building. First, we'll define some basic parameters (specifications) that our components need to meet. Don’t order the knobs I recommend, they do not fit. They should according to … Continue reading Lab Resistor Substitution Box – Part 2: Component Selection
Lab Resistor Substitution Box – Part 1: Design
Since our first few lessons covered resistors, and in at least one case demonstrated the utility of having a Resistor Substitution Box, that's what we're going to build for our first project. https://youtu.be/k5Fvy84lwG4 Introduction One of the most useful pieces of equipment in a hobby electronics lab is a good quality resistor substitution box. As … Continue reading Lab Resistor Substitution Box – Part 1: Design
