Conductors and Insulators...

Assignment: Last class we experimented with batteries, bulbs, wires, and a number of different materials (foil, cardboard, wax paper, etc..) to try to better understand the basic principles at work in most electrical technology...

1. Your assignment is to post web definitions for the following words:

electric circuit
electrical conductor
electrical insulator


Make sure to include your sources.



2. How can YOU define these in your own words based on our experiment with batteries, bulbs, wires, and different materials? How can you test to determine whether a material is a conductor or an insulator? How do you know when a circuit is a CLOSED circuit?
   


3. How do these concepts apply to your object? What parts are made of conductors? Insulators? How did you know? Are any circuits are present? How can you tell? Use pictures to explain, if you want.


4. What do you think a semiconductor is? Predict the meaning....Then look it up. Are there anny semi-conductors in your object. Where? What parts are made of semi-conductors and what special roles do they play?
