Electricity Basics Video Resources
What is Voltage?
Let’s take a close-up look at static electricity and voltage. In this first episode, we dive into the basics of voltage, how to calculate it and, of course, a few fun demos. We hope you’ll find this a valuable resource to use with students as an introduction to voltage through static electricity.
What is Electric Current?
We take a look at electric current and how it forms the basis for all modern electronics. We hope this series acts as a tie-in to introductory electronics and circuits lessons in many STEM classes.
Analyzing voltage and current in a circuit is a great place to start to understand what that circuit is doing. In this episode of “Adventures in Science,” we introduce the resistor and use it to help demonstrate Ohm’s Law.
When it comes to electric power, “work done” refers to the ability of the circuit to transform electrical energy into something else, like heat, motion or sound. “Work done” can also refer to transforming some other form of energy into electrical energy, as in a battery, which converts chemical energy to electrical energy.
Series and Parallel Circuits
Most basic electronic components (at least those with 2 terminals) can be connected in one of two ways: series and parallel. Series connections involve putting the components end to end so that they share a common node. Parallel means connecting the components so that they share two nodes (easy to visualize as side-by-side).
What is a Battery
Batteries offer a fantastic way to store electrical potential energy in the form of chemical reactions. We take a brief look at the fascinating history behind the invention of the modern battery and explain how they work, complete with animated hand-drawn diagrams.
