What are conductors?
They are what carry electric charges. Most conductors have many free electrons. A metal doorknob is an example of a conductor. Objects that generally do not conduct charges are called insulators.
During a thunderstorm in 1752, Benjamin Franklin flew a kite that had a metal tip connected to a silk string that acted as a conductor. A key was then attached to the string at a point near the ground. When Franklin touched the key it sparked and he could feel the electricity. Note that the next two who tried this extremely dangerous experiment were killed.
There is also a massive buildup of electrons in a cloud. You see lightning when the electrons are finally discharged or released to the ground.
4. Where does electrical energy come from?
When you plug in an electric fan, you are not really using electricity. Instead you are using electric power. The source of this power is a generator. Large generators supply huge quantities of electric power to your community.
When teaching, your goals must be straight cut. Create an outline if you have to.
