Section 1 quiz for the CASTLE Electricity Curriculum
1
10 pts
The diagram below shows a battery and two bulbs in sockets. Sketch connecting wires in a way that would allow both bulbs to light at the same time.
2
10 pts
2. Using your diagram from question #1 above, draw arrows to show where and in what direction charge moves through the wires based on the established convention.
3
10 pts
3. Describe what will happen if one of the bulbs in your diagram is removed from its socket. Explain your reasoning
4
10 pts
4. What is the difference between conductors and insulators?
5
10 pts
5. Draw a diagram of a testing circuit which could be used to determine whether or not an object is a conductor.
6
10 pts
6. Explain how to use the testing circuit in question 5 to identify conductors.
7
10 pts
7. Examine the diagram below (Figure 1) showing a battery and three identical bulbs without sockets. You have two wires available. Draw the two wires connected in such a way as to depict a continuous conducting path that will enable all three bulbs to light. Add arrows to the continuous conducting path to indicate the direction of charge flow, based on the convention described in Section 1.

10 pts
8. Figures 2 through 6 show a variety of possible connections with a battery, wires and two bulbs. For each figure decide which, if any, bulbs will light and draw a colored line showing the continuous conducting path. Circle the number of the bulb(s) THAT LIGHT.
9
10 pts
9. Figure 3 shows a possible connection with a battery, wires and two bulbs. Decide which, if any, bulbs will light and draw a colored line showing the continuous conducting path. Circle the number of the bulb(s) THAT LIGHT.

10 pts
10. Figure 4 shows a possible connection with a battery, wires and two bulbs. Decide which, if any, bulbs will light and draw a colored line showing the continuous conducting path. Circle the number of the bulb(s) THAT LIGHT.
11
10 pts
11. Figures 5 shows a possible connection with a battery, wires and two bulbs. Decide which, if any, bulbs will light and draw a colored line showing the continuous conducting path. Circle the number of the bulb(s) THAT LIGHT.
12
10 pts
12. Figures 6 shows a possible connection with a battery, wires and two bulbs. Decide which, if any, bulbs will light and draw a colored line showing the continuous conducting path. Circle the number of the bulb(s) THAT LIGHT.
13
10 pts
13. Describe evidence which indicates that bulbs light only when something is happening in the wires.
Indicate whether each of the following statements is True or False. Then state evidence which either supports or contradicts each statement.
14

14. The battery determines the direction of flow of charge in a circuit.
True
False

18. Light bulbs are non-directional devices. (Whichever way they are connected in the circuit, they behave the same way, even if you turn them around.)
True
False
