Basic Vocab Flashcards
Watt
Unit of power equal to volts x amps
Voltage
A type of “pressure” that drives electrical change through a circuit
Volt
Unit of potential difference (similar to pressure)
Transformation
The change in energy from one type to another as in a battery, which changes chemical energy to electricity.
Transfer
The movement of electrons from one place to another either by current of static.
Static Electricity
The build up of electrical charges on a surface produced by the contact and separation of dissimilar materials.
Series Circuit
A circuit that connects a source, load and conductors in a single loop. Any break in the circuit will stop the flow of the current.
Resistor
A device used to control current by providing resistance
Resistance
The degree to which a substance resists electric current.
Parallel Circuit
A circuit that splits into branches, a break in one branch will not stop current in the other branches.
Ohm
Unit of electrical resistance used to measure a material’s resistance to the flow of electric current.
Ion
An atom or group of atoms that has either gained or lost electrons and therefore has an electrical change.
Insulator
A material that opposes the flow of electric current
Electron
A subatomic particle with a negative electrical change
Electromagnet
A temporary magnet formed when electric current flows through a wire or other conductor
Electricity
A form of energy produced by the flow or accumulation of electrons
Direct Current (DC)
Electric current that flows in one direction only.
Current Electricity
Electricity that flows through a circuit, or a continuous unbroken path.
Conductor
A material through which current flows easily.
Circuit
A path of conductors that an electric current follows.
Capacitor
An electric circuit element used to store charge temporarily
Battery
A device that uses chemicals to generate and store electricity.
Ampere (amp)
A unit of electric current used to measure the rate of flow.
Amperage
The number of electrons that pass a given point at a given time.
