And... We're Back

Today was a big' ol review day for tomorrow's exam for B, C and F. Do make use of the previously-posted videos for electric fields and forces and look through the ones in the last post for general review, especially if you weren't in class today.

E Block worked on their Capacitors lab for which the write-up isn't due until Thursday. Capacitors separate charges when exposed to a potential difference and, therefore, act as storehouses of electrical potential energy when the plates are reconnected by a conducting wire. The RC-time constant concept won't appear on the test tomorrow, but basic ideas about capacitance, capacitors and potential energy will be addressed.

On Wednesday, we all start electric current with C Block working on a lab centering on Ohm's Law.
