2017 #1 Free Response Question - AP Physics 1 - Exam Solution

The video tutorial covers a question from the 2017 AP Physics exam, focusing on circuits with identical batteries and light bulbs. It explains how to rank the potential differences across light bulbs in different circuit configurations and discusses which circuit will deplete its battery first based on resistance and current. The tutorial emphasizes the importance of clear, coherent responses in exams and provides insights into scoring guidelines.

What is the main task described in the problem from the 2017 AP Physics One exam?

• To determine the power consumption of each circuit.

• To rank the potential differences across the light bulbs.

• To find the total resistance in each circuit.

• To calculate the current in each circuit.

In Circuit 1, how is the light bulb connected?

• Not connected to the battery.

• In parallel with another bulb.

• In series with another bulb.

• Directly to the battery.

Which light bulbs have the same potential difference as the battery?

• Bulbs A and B

• Bulbs C and D

• Bulbs B and C

• Bulbs A, D, and E

Which circuit will run out of usable energy first?

• Circuit 3

• Circuit 2

• All circuits at the same time

• Circuit 1

What happens to the equivalent resistance when a resistor is added in parallel?

• It doubles.

• It decreases.

• It remains the same.

• It increases.

What is the relationship between current and resistance in a circuit?

• Current is directly proportional to resistance.

• Current is inversely proportional to resistance.

• Current is equal to resistance.

• Current is independent of resistance.

What is emphasized in the scoring guidelines for the exam?

• The importance of correct numerical answers.

• The inclusion of multiple-choice questions.
