Which statement correctly describes the formation of an electric current?

A
A resistance causes electric charges to move from lower to higher potential.
B
A voltage causes electric charges to move from lower to higher potential.
C
A resistance causes electric charges to move from higher to lower potential.
D
A voltage causes electric charges to move from higher to lower potential.

For a constant voltage, how is the resistance related to the current?

A
Resistance is inversely proportional to current, so when the resistance doubles, the current is cut in half.
B
Resistance is directly proportional to current, so when the resistance doubles, the current is cut in half.
C
Resistance is inversely proportional to current, so when the resistance doubles, the current doubles.
D
Resistance is directly proportional to current, so when the resistance doubles, the current doubles.

Jason sees a news report about a traffic jam caused by a truckload of tires that spilled across the road. The next day in class, he uses the traffic jam as an analogy to explain electric circuits to his friend.Which is most likely the analogy that Jason used?

A
The cars represent moving charges, and the spilled tires represent an increased voltage that causes the current to decrease.
B
The cars represent moving charges, and the spilled tires represent an increased resistance that causes the current to decrease.
C
The tires represent moving charges, and the cars represent an increased resistance that causes the current to decrease.
D
The tires represent moving charges, and the cars represent an increased voltage that causes the current to decrease.
