Subject: [Phys-l] cars and physics
I'll be teaching electricity in the coming weeks. Wanted to do some
basic
math problems involving the electrical system of an automobile with a
12-V
battery. Does anyone know the power (or current) of car devices, or a
web
site that would have this information?
radio
low beams (50 W?)
high beams (60 W?)
heater
air conditioner
rear window defroster (72 W?)
cigarette lighter
