Electric Fields: Crash Course Physics #26

Last time, we talked about how charged particles exert electrostatic forces on one another. We calculated these forces using the charge of each particle: which can be either positive or negative, and the distance between them, and we did it with the help of Coulomb’s Law: the equation that tells us the force generated by […]

Electric Charge and Electric Fields

Professor Dave again, let’s discuss electric fields. We live in an age where we take electricity for granted. Just plug into the wall and you can power any device you want. But what’s in there? What is electricity made of? The discovery of a variety of phenomena over several centuries eventually led to our mastery […]

8.02x – Lect 4 – Electrostatic Potential, Electric Energy, Equipotential Surfaces

We’re going to talk about again some new concepts. And that’s the concept of electrostatic potential electrostatic potential energy. For which we will use the symbol U and independently, electric potential which is very different, for which we will use the symbol V. Imagine that I have a charge q one here and that’s plus, […]

Electrical Tricks of Biba Struja the Battery Man

Hi. Internet showed me another miracle man called Biba Struja. He started from humble beginnings. (At first glance, you would never…) He could hold live wires, and cook sausage with electricity holding wires, and set fire by sending electricity through his body. Later, he cooked more sausages and set more things on fire and also […]

8.02x – Lect 1 – Electric Charges and Forces – Coulomb’s Law – Polarization

I’m Walter Lewin. My lectures will in general not be a repeat of your book but they will be complementary to the book. The book will support my lectures. My lectures will support the book. You will not see any tedious derivations in my lectures. For that we have the book. But I will stress […]
