Lec 07: Capacitance and Field Energy | 8.02 Electricity and Magnetism, Spring 2002 (Walter Lewin)

assemble charges, I have to do work, we discussed that earlier. And we call that electrostatic potential energy. Today, I will look at this energy concept in a different way, and I will evaluate the energy in terms of the electric field. Suppose I have two parallel plates, and I charge this one with positive […]

Review of all Electricity and Magnetism Dimensions – AP Physics C

Bo: Hey guys. Billy: Hey Bo. Bobby: Hi Bo. ♫ (lyrics) Flipping Physics ♫ Mr. P.: Ladies and gentle people, the bell has rung, therefore class has begun. Therefore you should be seated in your seat and ready to review electricity and magnetism dimensions, because dimensions are your? Billy, Bobby, Bo: Friends. Mr. P.: That’s […]

Electricity & Magnetism Hand Rules (part one)

Electricity and magnetism are intently related. We use moving magnets to generate electric current, as with these turbines, and electric current to make magnets. Here I’ve set up a powerful magnet with a strip of aluminum foil running perpendicular to the magnetic field lines. Remember these from the last episode? Well, I’ve set up a […]

(2 of 2) Electricity and Magnetism – Review of All Topics – AP Physics C

Mr. P: Ammeters and voltmeters. An ammeter, you need to put in series, a voltmeter, you need to put in parallel. In order to measure the current, in order to put it in, you need to have it in series, right? In order to have little change to the circuit, you need to have as […]

Numerical Solutions to Thermal Field and Fluid Flow in Welding – Part 2

Welcome to the part-2 of the lesson on numerical solutions to the thermal field and fluid flow in welding. We are choosing the control volume approach for the discussion on this numerical solutions, because it is the same method we have used to derive the governing equations. And the overview of the process that is […]

Therefore, you should be seated in your seat, ready and excited to review everything we learned in electricity and magnetism in AP Physics C. Here we go, are […]

TCC2WORK – Welding

TCC graduates have exciting careers in fields like… Welding. It means a lot to me to be able to build things and put in the quality of the work and craftsmanship to make it look as perfect as I can. Careers start here. You’re next.

Soldering Without A Soldering Iron (Update Available)

This video is about soldering without a soldering iron in case you get stuck in a situation and and you can use things like cigarette lighters I’ve used matches, candles, what have you the trick here is this little piece you just make your normal connection where you twist the two wires together but this […]

Loram – Laborer

♪ It’s gonna be a life changer, it was for me. If I could look back and know that Loram was here, I’d probably have came to work for Loram sooner. As long as you come to work and you work hard, you’ll go places. I like to start my laborers out on maintenance. You’re […]
