Ohms Law

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. • This interesting law of physics was named after Georg Ohm, and states that the current between two points is directly proportional to the voltage across those two points: I = V/R • With a little bit of algebra, we can move the variables around and arrive at the more memorable: V = I x R • In the video, we demonstrate voltage and current in a fluid-based circuit, and show how a resistor acts like a piece of steel wool used to restrict the flow of water. We also construct a real circuit using a resistor, measure the voltage and current, and then calculate the resistance using Ohm’s Law. • The information in the video was inspired by the following tutorials: • Voltage, Current, Resistance, and Ohm's Law: https://learn.sparkfun.com/tutorials/... • Resistors: https://learn.sparkfun.com/tutorials/... • How to Use a Multimeter: https://learn.sparkfun.com/tutorials/... • I’ve gotten some good feedback on the previous tutorials, so thank you to everyone who commented! For this video, I put the “intuitive” demo first before touching any math, so hopefully that helps to make things clearer for students. What can be improved for episode 4?
