Objectives:
1. Learn the vocabulary for electrical circuits.
2. Understand and apply knowledge to how circuits conduct electricity.
Procedure:
1. Answer the questions. For help, go to the web pages by clicking on the blue links, Grolier, or the book resources.  2.  The last website, "physcci", has equation sheets.  Print them for use in the course.

( Electricity )

1. What is static electricity?

2. In static electricity, objects with like charges _____________________ each other.

3. What is an electromotive force (EMF)?

4. Metal that easily conducts electron flow is considered to have (low/medium/ or high) resistance.

5. Why do electricians avoid wiring with moderate resistance metal wire?

6. To separate the electron from the nucleus of the atom requires an input of

7. Electrical force is measured in what unit?

For the following questions see: Electric Circuits

8. Batteries are a form of what type of stored energy.

9. A common voltage for houses other than 110 volts is_______________.

10. What is the variable used to represent CURRENT?

11. Draw and Label the simple electrical circuit schematic with the letter to show what parts are responsible for voltage (V), current (I), and resistance (R).

12. A battery is often used to provide electricity. What type of energy transformation occurs to provide electricity?

13. In order for a light bulb in a circuit to turn on, the circuit must be _______________.

14. Explain how light emanates from a light bulb.

15. Write a paragraph explaining how electricity from a battery is used to power a flashlight. Include an explanation of the type of energy is used, how the battery produces electricity, and what creates light.

Physics is mathematics as well as concepts.  If you need help with the equations, go to Mathematics of Electricity

16. Use an algebraic equation to express the relationship between Voltage (V), Resistance(R) and Current(I).

The energy in a ___________________is called potential difference or electromotive force (EMF). The source of the

energy is from a cell or main supply and is measured in_____________ by a voltmeter. One volt is equivalent to move

one__________through a circuit with a resistance of one ohm.

What does one amp or ampere represent in relationship to “charge” and time?

There are other equation sheets to use in class at the following website:
