New Video about Resistivity!! Open vs. closed circuits are demonstrated. Conductors and insulators are shown in circuits. Resistivity is defined and the equation is analyzed. Resistivities of common materials are shown. Semiconductors are discussed. The temperature dependence of the resistivities of materials is demonstrated.
Balloon Excess Charges Experiment
Two 0.0018 kg balloons each have approximately equal magnitude excess charges and hang as shown. If θ = 21° and L = 0.39 m, what is the average number of excess charges on each balloon?
It's been some time since I shared positive feedback I receive for my work as Flipping Physics. Honestly, it is comments like these which keep me motivated to continue to make my videos. So, here are a few from this month so far. If you want to see more, you can always visit the "comments" page on my webpage.
Today Flipping Physics hit the 50,000 YouTube subscriber mark. I am humbled and amazed. Thank you to all who have helped support me in this free physics educational endeavor. Here's to hoping for 50,000 more!
Determining the Speed of the Electron in the Bohr Model of the Hydrogen Atom
Yep, I make physics videos in the hope that you can learn physics. If you are a physics teacher, I am very hopeful that you will want to use them to help flip your physics class.
