From the Massachusetts Comprehensive Assessment System Answer the following questions analyze simple arrangements of electrical components in both series and parallel circuits. Recognize symbols and understand the functions of common circuit elements (battery, connecting wire, switch, fuse, resistance) in a schematic diagram 1) The diagram below shows an electrical circuit with three bulbs and three
switches. The switches are labeled X, Y, and Z. When all three switches are
closed, as shown, all three bulbs are lit.
Which of the following statements describes what will happen if switch Z is
opened?
A. Only bulb 1 will be lit.
B. Only bulb 3 will be lit.
C.
All three bulbs will be lit.
D. None of the bulbs will be lit.
2) A circuit with three identical light bulbs is shown in the diagram below.
a. Identify the symbol labeled J in the circuit.
b. Describe what each light bulb does in each of the following situations:
• when switches 1 and 2 are open
• when switches 1 and 2 are closed
• when switch 1 is open and switch 2 is closed
• when switch 1 is closed and switch 2 is open
