Electric forces-the forces caused by the build-up of electricity
Stataic electricity- is the build up of electric charge on an object
Electric chargeAn object aquires static electricity when it has an excess build up of electric charge
Electric discharge-is the removal of an electric charge from an object.
Coduction of electricity-passage of electric charge through a material.
Ampere-the unit used to measure electric current; the symbol is A
Cell- A device that converts chemical energy in to electrical energy
Volt- Unit used to measure voltage; the symbol is V
Electrode- Part of an electric cell that allows electrons to enter or leave; it is usually made of a metal or carbon.
Electrolyte- A solution that conducts elctricity
Resistor- A device with a certain resistance to the passage of electric charges; used in electronic devices
Generator- A device that produces electrical energy from mechanical energy
Permanent Magnet- A piece of hard steel alloy that stays magnetised for a long time
Electromagnet- A coil of wire that becomes magnetised when a current exists in it
Thermocouple- Device consisting of a junction of two different metals; when heated, produced an electric current
Electric- Circuit an uninterrupted conducting path for an electric current
Switch- A device that can open or close an electrical current
Source- The part of an electric circuit that changes the energy into electrical
Conductor- A material that allows electric current to pass through it easily.
Control- The part of an electric circuit is opened or closed
Load-The part of a circuit that changes electrical energy into some other form of energy
Series CircuitAn electrical circuit with one conducting path and no branches
Parrallel Circuit-An electric circuit that provides alternate conducting paths for electric current.
Joule-The SI unit; for energy; the symbol is J.
Watt-Unit used to measure electrical power; the symbol is W.
Watt SecondsA unit of electrical energy equivalent to one joule.
Kilowatt Hour-The measurement of usage of household energy.
GroundedConnected so that a charge is conducted to or from the Earth.
