    • A. brighter than before
    • B. the same as before
    • C. dimmer than before

  2. Question 2

    True or false? Circuit diagrams use standard symbols.

    • A. True
    • B. False

  3. Question 3

    A circle with the letter M inside stands for…

    • A. a magnet
    • B. a motor
    • C. a mirror
    • D. a meter

  4. Question 4

    How many lamps (bulbs) are in this circuit diagram?

    Answer

  5. Question 5

    A buzzer is too quiet. What change to the circuit will make it louder?

    • A. Add another buzzer.
    • B. Use longer wires.
    • C. Add another cell.
    • D. Open the switch.

  6. Question 6
