Science Explosion v4, chapter 8

Question Answer
ampere unit to measure how much current flows through a circuit in 1 second
binary number system a system that uses open and closed circuits to communicate the number 0 and 1
circuit continuous unbroken path
conductor allows electricity to flow through easily
electric cell produces an electric current using 2 metals and a solution
electrical signal electric current that carries information
electrolyte liquid that conducts electricity
electromagnet coil of wire with a core attached to electrical source
insulator does not allow electricity to flow through
integrated circuit very small circuit with built in parts
magnetic field area of magnetic force
maglev magnetic levitation
magnet material that can attract iron
parallel circuit has multiple paths for the electricity to travel
resistor reduces flow of electrons
semiconductor conducts electricity better than insulators but not as good as conductors
series circuit has only one path for the electricity to travel
short circuit a short path for electricity which can cause sparks or fire
switch conductor that can be moved open or close a gap in a circuit
volt measurement of the amount of electrical force in a circuit
watt measurement of power (how fast work is done)
