what the title says, please tell me if there are typos

electricity

form of energy which can travel along conductors

energy

needed to do or change things, anything that can do work or make a change

static electricity

the build-up of of electrical charge on an insulator, electrical charge that remains on an object

charged particles

paraticles that carry electricity

matter

either solid, liquid or gas, that which has mass and occupies space

atoms

extremely small particles which all matter is made up of

electrons

negatively charged particles which orbit the nucleus of an atom

neotrons

neutrally charged paricles which are contained in the nucleus of the atom

protons

positively charged particles which are contained in the nucleus of the atom

nucleus

central core of an atom containing protons and neutrons

conductors

objects that electricity is allowed to pass through

insulators

objects that do not allow electrons to travel thourh

negatively charged

objects that have gained electrons making them... _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _

positively charged

objects that have lost electrons making them _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _

circuit

complete conducting loop where all components are linked together

free electrons

electrons which are able to to transfer through a substance

circuit diagram

simple way of drawing electrical circuits

terminal

point of attachment for wires to a battery or meter

current

the flow of electrons around a conducting circuit

series circuit

circuit in which all components are in a single 'loop'

parallel circuit

circuit in which there are two or more 'loops'

alternating current

AC current that keeps changing direction

amp

unit of current

direct current

lets the current travel in one direction only d_ _ _ e

fuse

a thin wire which melts if the current is too large

resistance

property which makes it hard for electrons to pass r _ _ _ _ _ _ _ _ _

resistor

a component used to limit the current in a branch/part of a circuit

rheostat

a variable resistor with a large coil of resistance wire (think of mood lighting)

ohm

unit of resistance

voltage

energy gained or lost by the circuit

power

total amount of energy supplied or used per second

watt

unit of power
