| ==== Project 14A: Transformers: Magnetic Flux in Disguise ==== | ==== Project 14B: More Practice with Induction === |
| | Below are three worksheets that cover induction and induced current. These problems focus on finding the direction of the induced current and calculating the induced voltage for simple scenarios (these problems will feel much more similar to the homework problems, rather than our typical in class problems). |

| | /*==== Project 14A: Transformers: Magnetic Flux in Disguise ==== |
| Back in Lakeview, the discovery of Dr. Watersa's illicit stash of jellybeans has shocked the town's residents. Not only has she been hiding delicious treats from her friends and neighbors, the town is also out-of-luck for the potential alternative energy source. In their anticipation of using the water mill for energy, the residents stupidly tore down all the ugly power lines. Now you have to help set them back up. You have access to a high-voltage power line from the edge of town, which has a voltage difference of $\Delta V = 240 \text{ kV } \cdot \sin(\omega t)$ compared to the ground, where $\omega = 60 \text{ Hz}$. You have access to the necessary safety equipment so you won't get electrocuted. You also have a plentiful supply of iron piping, which the town blacksmith has agreed to help you bend and mold as needed. Lastly, you have as much 12-gauge copper wire as you can imagine. Your goal is to devise a way to feed power lines to each house in Lakeview which don't exceed the maximum of 120 V compared to ground. | Back in Lakeview, the discovery of Dr. Watersa's illicit stash of jellybeans has shocked the town's residents.
