Electricity Unit Review
Part A:
Static Electricity
 The Law of Electrostatics
 Definition of Static Electricity
 Ways to create static electricity – friction, conduction and induction
 Friction – be able to use the electrostatic series to determine whether two objects
rubbed together would have a positive or negative charge
 Conduction – be able to draw before, during and after contact diagrams. Know
which way electrons would move when two objects are touched together and the
charges created (electrons always move from the more negative to the lesser
negative object and aim to create two objects with the same charge)
 Induction – be able to draw what objects would look like when there is a shift in
electron arrangement and that this shift is temporary
 Electric Discharge – what is it, when does it occur?
 Grounding – what is it, how is it done/what results?
 Useful Applications of Static Electricity
Part B:
Current Electricity
 Definition of current electricity – how is it different from static?
 Electric circuits – what are they? Why do we need circuits?
 What 4 components are parts of an electric circuit? Which one is optional?
 Know the function of each part of the circuit.
 Know the difference between an open and a closed circuit
 Two types of circuits – series and parallel – know the major differences between
the two – effect of adding lights, removing a light from the socket, the use of
switches, what kind of devices they are used in
 Schematic or Circuit diagrams – know how to draw diagrams for both series and
parallel circuits
 Current – definition, symbol, units measure it in and its symbol, how to measure it
and connect it into a circuit
 Potential Difference or Voltage - definition, symbol, units measure it in and its
symbol, how to measure it and connect it into a circuit
 Resistance - definition, symbol, units measure it in and its symbol, how to
measure it and connect it into a circuit
 Ohm’s Law – know what it states and how to calculate V,I or R in a given
problem – use GRASS (given, required, analysis, solve and sentence) for each
problem
 Current and Voltage in Series and Parallel Circuits – how they differ – know the
two equations needed to calculate voltage in a series circuit and current in a
parallel circuit
 Electrical Efficiency – calculation to determine efficiency, what does efficiency
mean, calculate cost
 Different methods of creating electrical energy
