If you’ve ever worked with guitar pedals or analog audio gear, you’ve probably realized the value of a resistor decade box. They substitute for a resistor in a circuit and let you quickly flick ...

A precision voltage divider produces a specific fraction of its input voltage using carefully matched resistive components.

The classic Schmitt-trigger-based RC oscillator is "hacked" and analyzed using the simulation software QSPICE.

"Learn how to set up and analyze an RC circuit using the PhET Simulator! In this tutorial, I’ll guide you through the step-by-step process of building a simple resistor-capacitor circuit, explaining ...
