Today's Lecture (9/21): |
| Summary: |
- To analyze circuits, we need a few basic definitions.
Electrical current is a measure of how much charge is passing
through a given area in a certain amount of time.
- For most ordinary materials, the current through
the material can be related to the voltage across it by a single constant.
This is called Ohm's Law and a chunk of material used in this
way is called a resistor.
- In a resistor, the electrical power dissipated
as heat (measured in watts) is given by the current times the voltage.

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.
