electricity Flashcards
a material that allows electrons to move easily through it
conductor
flow of electrons through a wire or any conductor
current
power source that acts as an electron pump and generates electric current by a chemical reaction
dry cell
area surrounding an electron that exerts a force or anything nearby with an electric charge
electric field
the rate at which electrical energy is converted to another form of energy
electrical power
device containing two suspended metal leaves in a jar that move apart when charged
electroscope
material that does not allow heat or electrons to move through it
insulator
unit of electrical energy
kilowatt-hour
states that potential difference= current•resistance
ohms law
electrical circuit where current flows through more than one path
parallel circuit
the difference in electrical potential energy between two different points
potential difference
opposition to the flow of electrons through a conductor
resistance
electrical circuit where the current has only one path
series circuit
net buildup of electrical charges of an object
static electricity
power source that generates electric current by a chemical reaction
wet cell
closed path through which electrons flow
circuit
