Electrical Vocab

TermDefinition
Amp The unit of electrical current.
Voltage The pressure from an electrical circuit's power source that pushes charged electrons through a conducting loop, enabling them to do work such as illuminating a light.
Ohm The SI unit of electrical resistance.
Resistor An electrical component that limits or regulates the flow of electrical current in an electronic circuit.
Parallel Circuit Has two or more paths for current to flow through.
Series Circuit A closed circuit in which the current follows one path, as opposed to a parallel circuit where the circuit is divided into two or more paths.
Capacitor A passive two-terminal electronic component that stores electrical energy in an electric field.
Ohm's Law A law relating the voltage difference between two points, the electric current flowing between them, and the resistance of the path of the current.
AC Current An electric current which periodically reverses direction.
DC Current The unidirectional flow of a electric charge.
Watt The unit of power.
Circuit A path in which electrons from a voltage or current source flow.
Electrical Ground The reference point in which the voltages are measured.
Conductor A substance in which electrical charge carriers, usually electrons, move easily from atom to atom with the application of voltage.
Insulator A material whose internal electric charges do not flow freely.
Joules (electrical) A derived unit of energy in the International System of Units.
Coulomb The standard unit of quantity of electricity in the International System of Units.
Resistance A measure of its opposition to the flow of electric current.
Transistor A semiconductor device used to amplify or switch electronic signals and electrical power.
Hertz The unit of frequency measurement.
