Electricity unit test

What are the types of particles in an atom What are the types of particles in an atom? What role do they play in the charge of an object? What is static electricity? Laws of Attraction and Repulsion What is an insulator? What is a conductor? Know some examples.

Know how to use the electrostatic series. Charging by conduction: friction vs contact (how does each work?) What is grounding? Why is it useful? What are two types of electroscopes? How do they work/identify charges? What is charging by induction? How is it different from conduction?

How can you permanently charge an object by induction? What is lightning? What are some practical uses of static electricity?

Current electricity Know the types of cells. Know the types of current: AC/DC. What is the difference between current, potential difference and resistance? How do you measure each? What are the factors that affect resistance?

Current electricity What is the difference between series and parallel circuits? Be able to draw circuit diagrams: know all symbols. Be able to use Ohm’s Law to answer questions and solve circuit analysis questions. Understand the current and voltage laws for series and parallel circuits for circuit analysis purposes.

Energy production/use What are the advantages and disadvantages of various energy generating processes? Renewable vs non-renewable resources. Calculate Energy, Percent Efficiency and Cost to Operate. How can you cut down on energy use?
