very small circuit with all the parts built into it
magnet
any material that has the ability to attract iron
parallel circuit
has multiple paths for electricity to travel
series circuit
has only one path for electricity to travel
conductor
material through which electricity cannot flow

switch
conductor that can be moved to close or open the circuit
magnetic field
area of magnetic force around a magnet
integrated circuit
signal information by opening and closing electrical circuits in sequence
Central Processing Unit (CPU)
brain of the computer that tells the other parts of the computer what to do
ampere
measures how much current flows through a given part of a circuit in one second
volt
measures the amount of electrical push, or force, in a circuit
watt
