I wish I had teachers like this when I was in school he is the best teacher I have ever seen.

29:35 "Not only is that stupid, but it's also very dangerous. So, let's do it." :D

lol at the guy below me

[Christina Li]

I like how he did the circuit problem!

[wensirui]

That happens when you replace the resistor by a wire, BUT, If R disappears,it means that the circuit is OPEN (CUT the wire and TAKE OFF the resistor), so the current cannot flow, it means the resistense is infinite large (resistence of the air).

I forgot, thank you MIT and all of your dedicated profs for making this series available. Also thanks to Google for being a great platform. It is a fantastic resource if used with discernment.

At 44 minutes, he begins the discussion on Lord Kelvin's remarkable discovery of a simple way to build up huge charges of static electricity using a few cans, some plastic tubes, and water.

yeah i forgot the circuit is open lol

8:12 I think there is a mistake. If R disappears then it is a conducting wire. But an ideal wire has no resistance (so the resistance is 0). There is a current but the potential difference is 0.
