1. The goal is to create a small alarm that goes off for exactly 6 seconds before turning off. The materials allowed are 1000 1 ohm resistors, wire, a box of rechargeable 1.5 V triple A batteries (12 count) and a piezoelectric buzzer.
2. Ohms Law. Power = V2/R
3. I have a design without the capacitor that is consistent of a piezoelectric buzzer, 200 1 ohm resistors, and 12 batteries so that the time for which my alarm sounds is around 3 days and 3 hours.
I'm not sure how to make it so that it sounds for exactly 6 seconds with a capacitor...
