Physics

1. Define static electricity. 2. State the rule of electric charge and give an example. 3. This is the most important question on the exam: List the three charging methods and give examples of them. What is the elementary charge, what sub-atomic particles have it, and why is it called 'quantized'? Why can only electrons move to cause a charge to occur? Does this charge have to be negative? Why? What are conductors and insulators? Give examples
