electric charge
A form of charge, either positive or negative, that exerts an electric force
Negatively charged object
An object that has fewer electrons than protons
Positively charged object
An object that has fewer electrons than protons
static electricity
And imbalance of electric charge on the surface of an object
charging by friction
The transfer of electrons between two neutral object made from different materials that occurs when they are rub together or come in contact (touch)
Electrostatics series
A list of materials arranged in order of their tendency to gain electrons
Charging by conduction
Charging an object by contact with a charged object
grounding
Connecting an object to a large body, like earth, that is capable of effectively removing an electric charge that the object might have
Conductor
A Material that lets electrons move easily through it
Insulator
A material that does not easily allow the movement of electrons through it
Electric discharge
The rapid transfer of electric change from one object to another
Electric circuit
A continuous path in which electrons can flow
Current electricity
The controlled flow of electrons through a conductor
load
The parts of an electric circuit that converts electrical energy into other forms of energy
Switch
A device in and electric circuit that controls the flow of electrons by opening or closing the circuit
Electrical energy
the energy provided by the flow of electrons in an electric circuit
Electric cell
A device that converts chemical energy into electrical energy
renewable resource
A natural resource that is unlimited (for example energy from the sun or wind) or can be replenished by natural processes in a relevantly short period of time (for example biomass)
Circuit
A way of drawing and electric circuit using standard symbols
parallel circuit
The circuit in which the loads are connected by branches so there are two or more paths for the electrons to flow
Siries circuit
The circuit in which the loads are connected end to end so that there is only one path for electrons to flow
Electric current
A measure of the rate of electron flow past a given point in a current circuit; measured in amperes
Ammeter
A device used to measure electric current
Voltmeter
A device used to measure potential difference ( voltage)
