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.

Question

Which is most likely the analogy that Jason used?

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

Answer 1

The most likely analogy that Jason used is:

The cars represent moving charges, and the spilled tires represent an increased resistance that causes the current to decrease.

In this analogy, the traffic jam (spilled tires) impedes the flow of cars (moving charges), similar to how increased resistance in an electric circuit impedes the flow of current. When there is more resistance in a circuit, the current decreases, analogous to how the traffic flow diminishes due to the jam.
