Question 1
1.
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.
Question 2
2.
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.
Question 3
3.
3. Describe what will happen if one of the bulbs in your diagram is removed from
its socket. Explain your reasoning
Question 4
4.
4. What is the difference between conductors and insulators?
Question 5
5.
5. Draw a diagram of a testing circuit which could be used to determine whether
or not an object is a conductor.
Question 6
6.
6. Explain how to use the testing circuit in question 5 to identify conductors.
Question 7
7.
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.
Question 8
8.
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.
Question 9
9.
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.
Question 10
10.
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.
Question 11
11.
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.
Question 12
12.
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.
Question 13
13.
13. Describe evidence which indicates that bulbs light only when something is
happening in the wires.
Question 14
14.
14. The battery determines the direction of flow of charge in a circuit.
Question 15
15.
15. What evidence do you have to support your answer to question 14 above.
Question 16
16.
16. A compass can be used to determine the exact direction that charge flows in
a circuit.
Question 17
17.
17. What evidence do you have to support your answer to question 16 above.
Question 18
18.
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.)
Question 19
19.
19. What evidence do you have to support your answer to question 18 above.
Question 20
20.
20. Non-metallic substances are generally conductors.
Question 21
21.
21. What evidence do you have to support your answer to question 20 above.
