Today's Lecture (9/17): |
| Summary: |
- If two objects are charged up with +q
and -q (by connecting them to a battery, for example) the voltage
between them will depend on the geometry of the system. A constant,
called the capacitance, can be defined that relates the charge
and the voltage.
- In general, you will have to find the
electric field (via Coulomb's Law or Gauss's Law) from the charges
and the geometry. Then you can do an integral to find the voltage.
The capacitance is found from what every constants you have.

Diversion-of-the-week: |
This week's diversion should help with
studying for exams by teaching you tricks for remembering things.
One way to do this is via memory
pegs. These are words or pictures to which you can attach a memory.
(The trouble is remembering to use the pegs ;-) Poke around this website
for other good exam advise, too.
