Compare and contrast ac and dc current.
Give an in-depth explanation of current flow.
Given the voltage, what is the
resistance of the light bulbs so that they glow the same?
Why is wall voltage ac and not dc?
What does R need to be to produce 10 A through the circuit?
The internal resistance of each battery is 1 ohm. Find the terminal voltage
across each battery.
Draw a diagram of two bulbs, a wire, a beer can, and a battery having both
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
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?
