Wheatstone Bridge Explained Simply | Measure Unknown Resistance

In this video, from Build Circuits With Rich, we explore the classic Wheatstone Bridge circuit — one of the most useful techniques for measuring an unknown resistance with high accuracy. In this video you’ll learn: • What a Wheatstone Bridge is and why it works • How the bridge balances and what that means • How to calculate an unknown resistor • Why this circuit is still used in sensors and instrumentation today This video is part of my beginner electronics series designed to help you understand circuits step-by-step with simple explanations, real examples, and hands-on demonstrations. 🔧 Full lessons, notes, and downloads available on my website: 👉 https://buildcircuitswithrich.com 📘 Want to learn electronics from the ground up?
