Today's Lecture (9/24): |
| Summary: |
- There are only three rules that are needed to
solve any circuit problem involving batteries and resistors (although
we'll see a few shortcuts soon).
- The first rule is simply Ohm's Law which states
that the voltage across a resistor is proportional to the current.
- The second rule is that the voltage around
ANY loop has to be zero.
For example, if you go around a loop with a battery and several resistors,
the voltage across the resistors has to sum to equal the voltage on
the battery.
- The third rule says that the current flowing
into a node equals the current flowing out.

Diversion-of-the-week: |
This week's diversion takes a page from
the Bizarre Stuff You
Can Make in Your Kitchen website and it's called the Wonderous
Glowing Pickle. Basically, if you plug a pickle into wall socket,
it glows! (Disclaimer: This is dangerous! If you don't know what you
are doing, you should probably just download the video of this trick!)
