Electricity and Magnetism Vocabulary List Atom Battery Cell Charge Circuit breaker Circuit Closed circuit Conductor Current Electricity Electrolyte Filament Fuse Insulated wire Insulator Kilowatt Load Smallest particle of an element that can exist and still have the properties of that element Device that generates electricity through a chemical reaction, made of one or more cell Contains positive and negative electrodes in an electrolyte A certain amount of electricity A safety device that prevents circuits from being overloaded. It can be reset once it is “tripped”. Complete path for an electric current Current flows from the battery through a device and back to the battery Anything that an electrical current can pass through easily The flow of electricity A type of energy in which electrons move through a device Liquid or paste that allows electrons to move easily through a cell Very fine wire Safety device used in a circuit to prevent overloading. A wire burns up. It must be replaced. Wire wrapped by plastic coating Material that electricity has a hard time flowing through, such as plastic coating wires, leather, wood, etc. Unit of electrical power equal to 1000 watts An electrical device such as a motor or light Negative charge Negative terminal Non-renewable resource Open circuit Parallel circuit Positive charge Positive terminal Power Renewable Resistance Resistor Series circuit Terminal Tungsten Voltage Wattage Watt Having more electrons than protons Point on the battery where electrons leave A natural resource that cannot be replaced, such as oil or natural gas An incomplete path, electricity cannot cross the break Provides more than one path for electricity to flow Having more protons than electrons Point on the battery where electrons enter The rate at which work is done – measured in watts Can be replaced Friction against electrons moving An electrical device which slows electrons down One path for the electricity in a circuit. If one load is disconnected, the circuit will not work. Organized and systematic steps to find out why your circuit is not working A metal element used in making filaments in light bulbs How much electrical energy is supplied. For instance, your house receives 120 volts. Power expressed in watts A unit used to measure power
