| + | Conceptual Questions: | ||
| + | - There are a lot of new vocab words this week. For each of these words, write out the variable, the definition (what is it in words), and the units: electron mobility, electron density, conductivity, | ||
| + | - How does the current compare in the filament and carrier wires? (Same, bigger, smaller?) How does the electric field, potential difference, and power compare for the different wires? | ||
| + | - What is the drift speed of the electrons in the wire? How long would it take one electron to travel the whole circuit? (You can calculate a numbers here.) Why would the lights turn on immediately when you flip a switch? | ||
| + | - What assumptions did you make in your solution? Why did you need them? | ||
| + | - What other factors might influence the choice of metal? How realistic is your solution? | ||
