| + | Conceptual questions: | ||
| + | - What would a flux versus time graph look like for the spinning loop? What would an induced voltage versus time graph look like? How are they related to one another? | ||
| + | - What would be the maximum amount of current produced by the water mill? Is it enough to power a town? | ||
| + | - What would be the differences between this sort of power generator and power generators in real life? | ||
| + | - What assumptions did you make to solve for the induced current? (Hint: some of them go into simplifying the magnetic flux integral) | ||
| + | - Why is there a negative sign in the induced voltage equation? | ||
| + | - How do the steps of the right hand rule from Wednesday relate to the math/ | ||
