1.
When atoms have an imbalance of protons and electrons, there will be a(n) _____________________________.
2.
_____________________________ is the measure of voltage flow.
3.
If a circuit is _____________________________ it means that electrons cannot flow through it.
4.
A(n) _____________________________ is a source of potential difference (check 16.2 notes).
5.
What is a typical dry cell battery made of: _________________________________________________________________.
6.
A(n) _____________________________ is an attractive or repulsive force caused by a charged object.
7.
A(n) _____________________________ circuit is a single pathway for current to flow.
8.
Resistance is measured in _______________________ and the symbol for this unit is _____________________.
9.
Larger wires usually flow more current decreasing the amount of _____________________________.
10. A(n) _____________________________ is a material that allows a charge to move through it.
11. List two examples of an insulator _________________________________________________________.
12. If you shuffle across a carpeted room on a dry day, you would transfer electrons from the carpet to your body. Is this an
example of a charge by contact OR a charge by friction?
13. If a circuit is _____________________________ it means electrons can flow through it.
14. Charges flow from ____________________________ areas to _____________________________ areas.
15. If an atom has an excess of protons, it will have a _____________________________ charge.
16. You shuffle across a carpeted room and build up a static charge. Then you touch your best friend on the arm and shock
him/her. Shocking your friend is an example of a charge by contact OR charge by friction?
17. Excess electrons = a ____________________________ charge.
18. A(n) _____________________________ consists of two plates made of different types of _________________________ in
a ____________________________ solution.
19. A(n) ____________________________ circuit has only a single pathway for current to flow.
20. A(n) _________________________ diagram is a graphical representation of a circuit.
21. Draw the symbol for the following:
a.
open switch - _____________________________
b.
closed switch - _____________________________
c.
wire(s) - _____________________________
d.
light bulb or lamp - _____________________________
e.
resistor - _____________________________
f.
battery - _____________________________
22. An example of a(n) _____________________________ circuit is when two or more devices are connected to a circuit and
the voltage is the same across each device.
23. _____________________________ is not a very good conductor so it is used as the filament in incandescent light bulbs.
24. A(n) _____________________________ is a substance that does now allow a charge to move through it.
