# Yr10 Electricity

TermDefinition
Atom The smallest particle of matter; made up of sub-particles (proton, neutron and electron).
Electricity Energy made available by the flow of electrical charge through a conductor.
Static Electricity Build up of electrical charge on an object due to friction
Electron Negatively charged subatomic particles
Terminal Connection point on a component in a circuit
Conductor A substance that allows heat or electricity to move through it easily eg copper
Insulator A substance which does not allow heat or electricity to move through it easily eg plastic, rubber, cork.
Battery A power supply created by a chemical reaction that produces an electrical force field to drive the current
Energy supplier Any object that creates a power supply eg battery , power pack, solar cells
Energy user Any object that converts the electrical energy provided by the power source into another form of energy eg light bulb, heater
Circuit A complete conducting pathway
Series circuit A circuit in which all the components are in the same loop
Parallel circuit A circuit in which components are connected in several branches
Bulb A component in a circuit that converts electrical energy to light energy; itâ€™s a type of resistor.
Current A flow of charged particles through a conductor
Voltage The energy gained or lost as the current passes through a component
Resistance The opposition to the flow of electrons through a substance
Ampere The unit for current
Volt The unit for voltage
Ohm The unit for resistance
Ammeter An instrument which measures the size of an electric current
Voltmeter A meter used to measure voltage gain or loss
Conventional current An electric current considered to flow from positive to negative
Variable resistor A resistor whose resistance can be varied; also known as rheostat.
Power station Where electricity is generated at a very high voltage to be carried around the country by the National Grid
Switch A component in a circuit that allows you to break and rejoin a circuit
Fuse A fuse is a thin piece of metal that melts easily if the current is too great
Magnetic field A region in which a magnetic force can be observed
Electromagnet A coil of wire wrapped around a core of soft iron. When there is a current in the wire, a magnetic field results.
Magnetic Poles The regions of a magnetic field where the forces appear strongest eg North and South
