| JPL has asked for a product report on your design. They would like you to outline which metals you would want to use for carrier and filament, why you picked those metals, and the expected surface charge distribution for your set up. They would also like to know the total resistance of your design and the total voltage needed to power your bulb (so they know what kind of battery to provide). | JPL has asked for a product report on your design.

| + | 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? | ||

| + | Conceptual Questions: | ||
| + | - How can you tell if two resistors are in series? Out of current, resistance, & voltage, what would HAVE to be the same for resistors in series? What would be different? | ||
| + | - How can you tell if two resistors are in parallel? Out of current, resistance, & voltage, what would HAVE to be the same for resistors in parallel? What would be different? | ||
| + | - How would you come resistors (series or parallel) to decrease the total resistance? What about to increase the resistance? | ||
| + | - What is the loop rule in circuits? What conservation principle is it related to? | ||
| + | - What is the node rule in circuits? What conservation principle is it related to? | ||
| + | - What steps do you need to follow in order to use loop/node rules? | ||
