Electricity Flashcards
Ammeter
A device used to measure current in a circuit
Ampere
Unit of electric current
Battery’s
Device that converts chemical energy to electrical energy. Energy comes out the -
Circuit
A path for an electrical current to flow around.
Closed Circuit
A complete circuit through which electricity flows
Circuit Diagram
A drawing that traces the path that electron flow will take in an electronic circuit.
Component
A part or element of a large whole
Current
A flow of electrical charge
Electron
Negatively charged particle
Lamp
Light bulb
Ohm
A unit of electrical resistance
Open Circuit
An incomplete circuit through which electricity will not flow
Ohm’s Law
The current in a circuit equals the voltage divided by the resistance.
Resistance
A material’s opposition to the flow of electric current.
Resistor
A device used to introduce some amount of resistance into a circuit.
Switch
A device that opens or closes a circuit
Volt
Unit for measure voltage. V= IxR
Voltage
Measure of how much energy in the circuit.
Voltmeter
A device used to measure voltage
Wire
A thin, flexible thread of metal
Positive Terminal
The point on the battery where electrons enter
Negative Terminal
Energy flows out of it into the circuit back to the positive terminal. (Battery.)
Series Circuit
An electrical circuit with a single path
Parallel Circuit
A circuit that contains more than one path for current flow
