Document Summary
Chapter 21 : coulomb"s law types of electric charge: electric charge. Electric charge electric charge is a fundamental property of the elementary particles out of which matter is made of there are two distinct types of electric charge, positive and negative same charges repel each other oppsite charges attracts. Nonconductors/insulator: are materials charge cannot move freely semiconductors : material that is between conductor and insulator superconductos: perfect conductor mobile electrons are called conduction electrons. Only conduction electrons can move psoitive ions are fixed in place. An objec can become positively charged only through the removal of negative charge. There is a conducting path between the rod and the earth"s surface which is a huge onductors charges get grounde when it reach the ground. Induce charge positive and negative charges have been separated due to hte presence of a nearby charge. If two charged particles are brought near each other, they each exert an electrostatic force on the other.
