- 1Static ElectricityBuild up of Static is caused by Friction
- 2Electrons in Static ElectricityOnly Electrons Move - Never the Positive Ones
When electrons are removed from particles the particles are left positively charged - Ions - 3Opposite2 Things with Opposite Electric Charges are attracted to each other
2 Things with the Same Electric Charge will repel each other - 4Electric CurrentElectric Current is a flow of charge round a circuit
- 5CurrentA current depends on a voltage and Resistance
Current will only flow through a component if there's a voltage across that component - 6PowerRate of Energy Transfer
Anything that supplies Electricity is also supplying Energy - 7Electrical Power EquationPower = Voltage X Current
- 8SymbolsPower - (W) - Watt
Voltage - (V) - Volts
Current - (A) - Amps - 9VoltmetreMeasures potential Difference Between 2 points
- 10Potential DifferenceThe Proper Name for Voltage
How much energy transferred to or from each unit of charge as it moves between 2 points - 11Circuit Symbols
- 12Resistance EquationResistance = Voltage / Current
