The following notes on static electricity were taken and then the class preformed the Lab on page 292 in the textbook.
Types of Electric Charge -Static Electricity is caused by the accumulation of charges on an item, knows as an insulator -Current Electricity is caused by the movement of charge through an object, known as a conductor -Insulators do not allow electrons to move easily Ex. oil, fur, rubber etc. -Conductors do allow electrons to move easily Ex. copper, gold, aluminum etc. -An object is 'grounded' when it is connected to earth (<3), so missing electrons or extra electrons can be balanced. Earth is so big (and beautiful) that it can receive many electrons. Law of Electric Charge -protons have a (+) charge and electrons have a (-) charge -opposite charges attract and like charges repel -only the electrons are transferred The physics test will be this Thursday! We will review for the entire block before the test - come prepared with questions to ask :) Comments are closed.
