I'm a high-school junior in AP Physics 1. My class was assigned an optional, grade-boosting project where we could make a circuit under certain guidelines. I figured I'd give it a shot, but I'm really struggling at the design. Here are the guidelines:
- You can only use wires, 4 switches, 3 lights, and one power source, and apparently now diodes
- Switch 1 is a master switch, and must turn on all three lights while the other 3 switches are open
- Switch 2, 3, & 4 must turn on an individual light while switch 1 remains open.
I have been using the Circuit Construction Kit from PhET found here, and I have really struggled. No other components are allowed. I eventually have to physically build the circuit and get the calculations of the current and voltages for each scenario, but I wanted to just get the design down. Any solutions or tips would be greatly appreciated!
EDIT: Here is the original assignment page given. I am going to try to clarify with my professor about what components are allowed.
EDIT 2: I have just talked with my teacher, and it seems that diodes are allowed, but NOT multi-way switches. He was very explicit about that.
