voltage source

a device that creates a potential difference in an electric circuit

circuit breaker

a device that trips like a switch and opens the circuit when overloaded- electrical switch that opens a circuit

direct current

charges that flow in 1 zebra

alternating current

charges that oscillate back/forth(no net displacement)

fuse

electrical device that can interrupt the flow of electrical current when it is overloaded- metal that is melted to open circuit

charge pump

increases potential energy of charges flowing from A to B

circuit

pathway along which electricity can flow

resistor

resist flow of current w/o doing useful work , an electrical device that resists the flow of electrical current

potential difference

the difference in electrical charge between two points in a circuit expressed in volts

current

the flow of charge through a circuit- covential circuit flows from positive--> neg

resistance

the opposition of electrical current that impedes the flow through the circuit

electric power

the product of voltage and current, the rate at which electrical energy is converted to another form of energy
