### Electric Circuits

TermDefinition
ammeter measures how much electricity is flowing around a circuit
amp (A) the unit for current
cell a source of electricity with a low 'energy'. Cells push electrons around a circuit
circuit a complete loop that electricity flows around
component something in a circuit, like a bulb, switch or motor
conductor a material that lets electricity flow through it
electric current the flow of electricity around a circuit
insulator a material that does not let electricity flow through it
mains (electricity) Alternating current at 230 V provided to houses , shops, etc
power pack a source of electricity with a low energy (low voltage)
switch turns electricity on or off, by closing or opening a gap in a circuit
voltage a way of saying how much energy is transferred by electricity
atom the smallest part of an element
electrical energy the kind of energy carried by electricity
electron tiny particle that flows around a circuit
filament thin piece of wire inside a light bulb that glows when electricity is flowing through it
model a scientific way of thinking about how things happen
resistance a way of saying how difficult it is for electricity to flow through something
resistor a component that makes it difficult for electricity to flow - resistors are used to control the size of the current in a circuit
variable resistor a resistor that can be adjusted to change the amount of resistance it has
parallel circuit a circuit with two or more wires running next to each other
series circuit a circuit where there is only one loop of wire
fuse a piece of wire that melts if too much electricity flows through it
electric shock when electricity flows through the body
impulse electrical signal carried by a nerve cell
