2014, High School Intro Physics

  Question 12: Open-Response  
A circuit diagram is shown below.
A rectangular diagram of a circuit consisting of three equal adjacent squares. The component on the left side of the left square is represented by two sets of alternating longer and shorter parallel lines with white space between them.
In your Student Answer Booklet, draw this circuit diagram and add four identical light bulbs (W, X, Y, and Z), two switches (S1 and S2), and two fuses (F1 and F2). Your arrangement of these components must meet the requirements listed below. Be sure to read all of the requirements before adding the electrical components.
  • Light bulbs W and X have the same brightness.
  • Light bulbs Y and Z have the same brightness and are brighter than light bulbs W and X when all switches are closed.
  • The first switch (S1) controls only light bulbs W and X, and the second switch (S2) controls only light bulbs Y and Z.
  • The first fuse (F1) protects only light bulb Z, and the second fuse (F2) protects the entire circuit.
Use the circuit components shown below. Be sure to label all of the components with the labels given.
The circuit components diagram contains:
W, X, Y, and Z, each represented by a circle with a horizontal line with one loop inside the circle S1 and S2, each represented by two unconnected black dots with a line jutting diagonally out from the left dot, and F1 and F2 each represented by two black dots connected by a wavy line.

Scoring Guide and Sample Student Work
