Questions
1. What is a circuit? 2. True or False: Resistance= Voltage/Current. 3. What unit is resistance measured in? 4. True or False: A series circuit has many paths for electricity. 5. What is an anion and cation? 6. What is static charge, and how do you get shocked? 7. What is an electric field, and how does it affect other atoms when they are not even touching? 8. What is an insulator, and what material is most used as an insulator? 9. What is Ohm’s law? 10. How many paths does a series circuit have for electric current to follow? 11. As resistance increases, what happens to current? What happens to voltage? 12. What is a parallel circuit? 13. What type of circuitry is your house an example of? 14. As voltage increases what also increases? 15. In series lights if one stops working do the rest keep working or does the current stop and the lights do not function? 16. What is resistance measured in? 17. What I current measured in? 18. What unit is amount of electricity measured?

Answers
1. A circuit is a closed electrical pathway. 2. True 3. Resistance is measured in ohms. 4. False. 5. An anion is a negativly charged ion. A cation is a positivly charge ion. 6. A static charge is an imbalance of electric charge caused by the rubbing of two or more objects together. For example when walk across the floor electrons rub off on your feet and are attracted to the door nob so you get an electric charge. 7. An electic field is the energy that holds electrons in orbit around the nucleus. When a positivly charged atom comes near a negativly charged atom they are attracted. An atom with a positive charge are repelled from another positibly charged atom. 8. An insulator is a material that does not conduct electricity. Rubber is most often used as an insulator. 9. Current = Voltage / Resistance 10. One 11. Current decreases and voltage stays the same. 12. A parallel circuit is a circuit with more than one path for electricity to follow. 13. Parallel circuitry 14. Current 15. The current stops and the lights do not function 16. Ohms 17. Amps 18. Volts
