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.
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.
