Those Guys
- Light
Draw a diagram of two bulbs, a wire, a beer can, and a battery having both
bulbs illuminated.
- Regular
A material has a resist[ivity] of 10 ohm[-cm].
What is the resistance of this beer
can (assume it as a solid cylinder).
3 cm high, 2 cm diameter
- Ice
An 8 oz. can, a 12 oz. can, and a 16 oz. can are connected in a circuit as
follows with resistance of 10 ohm, 15 ohm, and 25 ohm respectively.
What is the voltage across the 12 oz. can?
