Definitions Flashcards
Definition of electric charges
Charged particles that exert a force on each other
Definition of static electric charge
Electric charge that builds up on the surface of an object. Charges are “static” because they remain almost fixed in one location on the surface of the object until given a path to escape.
Definition of electric discharge
Charges are transferred very quickly like Sparks
Definition of conduction
The movement or transmission of electrons through a substance
Definition of current electrical energy
The flow of electric charge in a circuit
Definition of ampere
The standard unit for measuring electronic current
Define electrochemical cell
A package of chemicals that converts chemical energy into electrical energy that is stored in charged particles
Definition of battery
A combination of electrochemical cells
Definition of volt
The standard unit of measuring voltage
Definition of electrode
A metal strip that reacts with an electrolyte
Definition of electrolyte
A liquid or paste that contains chemicals that form ions and conduct electric charge
Definition of resistor
A material that can slow current flow in a circuit such as the filament in a light bulb
Definition of generator
A device that transforms the energy of motion into an electric current
Definition of electric circuit
A complete path in which electrons can flow- includes energy source, electrical load, and conducting wires
Definition of switch
A device that turns the circuit on or off by closing or opening the circuit
Definition of conductor
A material that allows the movement of electrons
Definition of electrical load
A device that converts electrical energy to another form of energy
Definition of series circuit
An electric circuit in which the components are arranged one after another; an electric circuit that has only one path along which electrons can flow
Definition of parallel circuit
An electric circuit in which the components are arranged in a parallel paths; an electric circuit that has multiple paths along which electrons can flow
Definition of grounding
The process of connecting a charged object to Earth’s surface
Circuit with multiple paths
Parallel
Circuit with one path
Series
Converts electrical energy to a different form of energy
Electrical load
