Electrical, Plumbing, Irrigation, Drainage And Other Accesories Flashcards
A fundamental quantity in electricity (+ or -)
Charge
The flow of electrons through a material.
Current electricity
The buildup of charges on an object.
Static electricity
The flow of electrons
Electricity
The basic unit of matter that contains a positively charged nucleus surrounded by electrons.
Atom
Negatively charged particles in an atom.
Electrons
Neutrally charged particles of an atom.
Neutrons
Positively charged particles of an atom.
Protons
The path an electrons takes through an atom or molecule.
Orbital
A device that converts mechanical energy into electricity.
Electrical generator
A device that changes the voltage of electricity so that it can be transferred over long distances.
Transformer
A material through which a charge moves easily
Conductor
A material that is usually insulating, but becomes conductive through the addition of an impurity.
Semiconductor
A material that has no electrical resistance; occurs near absolute zero.
Superconductor
A material that does not allow heat or electrons to move through it easily.
Insulator
A solid conductor through which a current enters or exits a medium.
Electrode
A electrode where free electrons are produced.
Anode
One or more cells connected in series.
Battery
An atom that has acquired an electrical charge.
Ion
An electrode where reduction occurs.
Cathode
A material that dissolves in water, producing a solution that conducts electricity.
Electrolyte
Any path that electrons can flow through.
Circuit
A circuit with a break in its path.
Open circuit
A circuit with a complete path, which allows for charges to move.
Closed circuit
The electrode held by the skin care specialist during a treatment
Active electrode
Is a rapid oscillating cycle that alternates back and forth, allowing electrons to flow first in one direction and then in the other.
Alternating current
A unit of electric strenth
Amp
Indicates the number of electrons flowing through a particular line.
Amp rating
Allows an alkaline solution to enter the skin when assisted by galvanic current and the negative pole of an electrode.
Anaphoresis
