Electrical properties Flashcards
Rheostat
Continuously variable resistor
Electrolyte
Liquid or paste that conducts electricity because it contains ions
Resistor
Substance that resists the flow of electricity
Electrode
A conductor which electricity enters or leaves a material or device
Wet cells
Electrochemical primary Cells having a liquid electrolyte
Charge separation
Concentration of like charges in specific areas of a neutral object
Voltage
A measure of how much electrical energy a charged particle carries
Breaker
A device that opens up a circuit if too much current is running through it
Electric current
Steady flow of charged particles
Electrical discharge
Sudden transfer of electrical charge from one object to the next , shown as a spark
Ampere
Unit that measures the rate of flow of an electrical current
Static electricity
Stationary electrical charge
Current electricity
Electricity that travels through wires and flows continuously
Current electricity
Electricity that travels through wires and flows continuously
Load
Device in a circuit that converts electrical energy to another type of energy
Circuit
A pathway for electricity to travel
Electrolysis
Process used to separate useful elements from solutions
Fly ash
Fine airborne ash produced by burning coal
Fuel cell
Primary cell that generates electricity directly from the chemical reaction with a fuel
Electromagnetic induction
Generations of electric current in a conductor by a changing magnetic field
Power
Rate at which a device converts energy
Geothermal energy
Energy deprived from the internal heat of the earth
Thermocouple
Device consisting of two wires that can generate electricity
Armature
Rotating shaft or coil in a motor or generator
