Monday's exam

The exam will be low-key, and you should have plenty of time. Here's the basic format:

• six questions total
• three questions on circuits (dc; resistors and batteries only)
• three questions on the magnetic field from wires (straight or circular; superposition)
• answer any three of the six

I'll provide a full formula sheet, you're free to bring in one sheet of your own paper just as last time.

I think you can probably solve three problems and be done in less than 90 minutes, some of you certainly in about 60 minutes. They are not hard problems compared to the homework, and a few of them are drawn from PH102 homework in fact.

If you're cramming now, I would suggest reviewing the solution to the field from a finite segment of current-carrying wire, and the battery charging problem from Hw4. HW4 partial solutions will be out in a couple of minutes.
