Class Vocabulary

Vocabulary TermDefinition
A current formed when electrons flow in one direction, followed by a flow in the opposite direction.
A silvery white metal that is soft, light, and an effective conductor.
A unit of measurement that indicates the amount of current flowing in a circuit.
The smallest distinguishable unit of a material that maintains that material's characteristics.
A device that converts chemical energy into electrical energy. Batteries produce direct current.
A completely enclosed path consisting of various devices that contains an electrical current.
A device used to convert an alternating current into a direct current.
A material that is very effective at conducting electricity. Metals are generally excellent conductors.
The device that affects or alters the flow of current in a circuit. The control can turn the circuit on or off, or it can perform more sophisticated tasks.
A reddish metal that is very ductile, thermally and electrically conductive, and corrosive resistant. Copper is often used to make electrical wire.
The flow of electricity through a circuit. Current is measured in amperes (or amps).
The time it takes for current to flow, pause, reverse direction, and pause again in an alternating current.
A current formed when electrons flow in one continuous direction.
Energy in the form of a flow of electrons.
The smallest part of the atom that revolves around the positively charged nucleus. Electrons have a negative charge, and they are the basic source of electricity.
A machine with a rotating component that converts mechanical energy into electrical energy.
A unit of measurement indicating a single cycle in an alternating current.
A unit of measurement that indicates the amount of electrical power in larger devices. Horsepower is used instead of watts to describe many electric motors.
A material that is highly resistant to the conduction of electricity. Ceramics and polymers are excellent insulators.
A unit of electrical power that equals 1,000 watts.
The device that converts electricity into another form of energy, such as heat, light, or motion. The load uses the current in a circuit to perform work.
An industrial machine that uses a rotary cutter to remove material from a part supported on its worktable.
A unit of measurement that indicates the amount of resistance in a circuit.
The law describing the relationship between voltage, amperage, and resistance. Ohm's Law states that volts equals amperes multiplied by ohms.
A circuit that contains multiple loads and multiple paths for the flow of current.
The part of a circuit that directs the flow of electricity from the source to the load. Copper wire is used as the path in most circuits.
A value used to calculate the correct wattage for a circuit with an alternating current.
A particle with a positive charge that is located in the nucleus of an atom.
The opposition to the flow of current in an electrical circuit. Resistance is measured in ohms.
A circuit that contains multiple loads but only one path for the flow of current.
A circuit that contains some loads connected in series and other loads connected to form multiple paths for electricity.
A silvery white metal that has the highest electrical conductivity of all metals. Silver is also fairly expensive.
The device that supplies the current that flows throughout a circuit. Examples of sources include batteries and generators.
A unit of measurement that indicates the amount of voltage in a circuit.
The electrical force or pressure that causes current to flow in a circuit. Voltage is measured in volts.
The amount of voltage that exists across two points of an electrical circuit.
A unit of measurement that indicates the amount of electrical power in a circuit.
