Key vocabulary for electricity, circuits, conductors, and insulators.

Flashcards

Electricity: The flow of electrons through a conductor.
Electric current: The rate of electron flow through a circuit; measured in amperes (amps).
Voltage: Electrical pressure that pushes electrons through a circuit; measured in volts.
Resistance: Opposition to electron flow through a material; measured in ohms.
Conductor: Material that allows electricity to flow easily; examples: copper, gold, silver.
Insulator: Material that resists electricity flow; examples: rubber, plastic, wood, glass.
Circuit: A closed path through which electric current can flow.
Series circuit: A circuit with only one path for current; all components are in the same loop.
Parallel circuit: A circuit with multiple branches; each component has its own current path.
Switch: A device that opens or closes a circuit to control the flow of current.
Battery: A device that converts chemical energy into electrical energy to power a circuit.
Ampere (amp): The unit used to measure the amount of electric current.
Volt: The unit used to measure voltage (electrical pressure).
Ohm: The unit used to measure electrical resistance.
Open circuit: A broken circuit where current cannot flow because the path is incomplete.
