In this tutorial, we’re going to answer your burning question: “What is a capacitor?”! Capacitors are one of the most basic components used in electronics and most all of our projects incorporate a capacitor in some form or another. Understanding how they work and how to use them is a skill most beginners should learn. […]
In this tutorial we’re going to answer the fundamental question that you’ve all been asking recently, “What is a diode?” A diode is a fundamental component that is at the very basics of many electronics projects. Unlike some of the passive components we’ve talked about recently (like resistors), a diode is a semiconductor. And as […]
You’ve probably seen resistors in most of the projects we do here at The Geek Pub, and wondered to yourself “What is resistance?”. Well today we’re going to do a tutorial on resistors and learn exactly what resistance is and how it works! How Resistance Works In our voltage tutorial we discussed how voltage seems […]
Many of you may not be familiar with just how handy a multimeter can be! A multimeter is a handy electronics meter that test voltage, resistance, and continuity in its most basic form. More advanced multimeters can even measure capacitance and temperature. In this tutorial, we’re going learn the basics of how to use a […]
In our first tutorial about basic electricity, you learned that current is just the flow of electrons in a wire. You learned about current and that its unit of measurement Amps refers to how many electrons are flowing past a certain point per second. In this tutorial we’re going to answer the questions you’ve all […]
This is new set of tutorials on the basics of electricity. I am often asked some of these questions, and I thought it would a great idea to have a place to share and send people to for the answers. Today we’re going to answer the question “What is current?” It’s a confusing topic and […]
