P5 Electric Circuits

Pregunta	Respuesta
Static Electricity	Build up of Static is caused by Friction
Electrons in Static Electricity	Only Electrons Move - Never the Positive Ones When electrons are removed from particles the particles are left positively charged - Ions
Opposite	2 Things with Opposite Electric Charges are attracted to each other 2 Things with the Same Electric Charge will repel each other
Electric Current	Electric Current is a flow of charge round a circuit
Current	A current depends on a voltage and Resistance Current will only flow through a component if there's a voltage across that component
Power	Rate of Energy Transfer Anything that supplies Electricity is also supplying Energy
Electrical Power Equation	Power = Voltage X Current
Symbols	Power - (W) - Watt Voltage - (V) - Volts Current - (A) - Amps
Voltmetre	Measures potential Difference Between 2 points
Potential Difference	The Proper Name for Voltage How much energy transferred to or from each unit of charge as it moves between 2 points
Circuit Symbols	Image: 57f68bbf-9a1e-4242-9da1-3fb95353874f (image/png)
Resistance Equation	Resistance = Voltage / Current
