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
