Electricity Information Hunt 1
Directions: Log on to our class website. Once you are there, use the Introduction to Electricity Notes and the Basic Electricity Notes to find the answers to the questions below. You will have to read through and think about both sets of notes to answer many of the questions below.
1. What are the two types of electricity and how are they different?
2. Why is rubber a good insulator, but not a good conductor?
3. Why is copper a good conductor, but not a good insulator?
4. What is happening when you ‘trip a breaker’ or ‘blow a fuse’? Why is this so dangerous?
5. In your own words, describe how a circuit works.
6. How are electrical devices using 120 volts different from devices using 240 volts?
7. You are in your home and observe many electrical devices that need to be fixed. Whoever fixes them needs to consider all the safety precautions during repair. Summarize, in your own words, five of what you feel are the most important safety precautions for a person fixing your electrical products.
8. Which characteristic of electricity is the one that will hurt you the most, amps, volts, watts, or resistance? Why?
9. How are the two types of current that can be used to power objects different? Give two examples of something that runs on each type of current.
10. What is GFCI?
11. Where would GFCI be used and why?
12. How are volts, amps, and watts different from each other when we discuss electricity?
13. What are the following wires used for - red, black, white, green?
14. How do the colors of wire and the colors of the screw correspond?
15. What are three general rules-of-thumb to use when wiring? (Hint: Think about the wires connected to screws, screw colors, and wire colors.)
16. How is a 14-2 cable different from a 12-3 cable?
17. Why is it important to know the colors of the wires in a cable?
18. Would it ever be possible to have a bare wire in an electrical circuit? Explain.
19. Why is it important to know the colors of screws on all electrical devices?
20. Does the color of wire nuts (connecting caps) tell you anything? If so, what?
21. Develop a chart that shows the schematics (pictures) that represent the following items: each type of wire, each type of switch, keyless light fixture, duplex receptacle, and each type of screw.
22. How can the understanding of electricity benefit you in your life?
