My school doesn't have very many adequate supplies (my physics classroom only has crappy wires, switches, batteries, resistors, voltmeters, ammeters, and pigeon bulbs). What's the best way to prepare for the lab portion of the event?
You can go to an electronics store (I used overpriced radioshack before) or shop online... Buy a breadboard, various resistance color coded resistors... An LED, decently sized capacitor... Just some stuff you can play around with. Perhaps buy a better multimeter. I don’t know if the lab gets too tricky... And some jumpers
