Electronics Foundations: Fundamentals

  • Course details

    Working with electronics can be a ton of fun, but it can also be a bit confusing—especially when you're first learning. In this course, electrical engineer Barron Stone uses easy-to-understand analogies to break down the fundamental concepts of voltage, current, resistance, and power. After you review the science behind electricity, Barron applies those concepts to build basic circuits. He explains the differences between the ideal, theoretical power sources that we often consider when designing circuits and the physical limitations of the real-world power sources that we actually use to build them. He also shows you how to use the go-to tool for debugging electronics—the digital multimeter—so you can measure the actual voltage and current in your circuits.

  • Welcome

    - Working with electronics is a ton of fun, but it can also be a bit confusing, especially when you're first learning. What is voltage, current, resistance, power? Sure, you could look up their definitions, but to really understand those concepts and how they relate to each other, that's key to working with electronics. I'm Barron Stone, and I'm an electrical engineer who likes to keep things as simple as possible. In this course, I'll demonstrate the fundamental concepts of voltage, current, resistance and power using analogies that are easy to understand. Electricity can be a difficult concept to grasp because we can't directly see it, so I'll use analogies to relate electricity to some things we can see, like water. I like to think of electrons moving around in a circuit like water flowing through pipes, because it helps me to visualize what's going on. In addition to knowing about the math and theory behind circuits, it's important to have a practical sense of what electronic…
