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.

Based on the given options, the suited choice is B.) The cars represent moving charges, and the spilled tires represent an increased resistance that causes the current to decrease.

Explanation :

The flow of electrons in a circuit is termed as electric current.

The materials which oppose the motion of the electron are called resistance of the circuit.

We know that Ohm's law is mathematically stated as :

V = IR

Where

V is the voltage

I is the current flowing

R is the resistance of the circuit

A traffic jam caused by a truckload of tires that spilled across the road. The truckload of the tires shows the effect of resistance because this opposes the motion of other vehicles on the road.

To explain the electric circuit to his friend, the analogy used by him is "The cars represent moving charges, and the spilled tires represent an increased resistance that causes the current to decrease".

So, the correct option is (B).
