Chpt. 11 - Basics Of Electricity Flashcards
ACTIVE ELECTRODE?
Electrode used on the area to be treated.
ALTERNATING CURRENT?
Rapid and interrupted current, flowing first in one direction and then in the opposite direction.
AMP?
Unit that measures the amount of an electric current (quantity of electrons flowing through a conductor).
ANAPHORESIS?
Process of forcing liquids into the tissues from the negative toward the positive pole.
ANODE?
Positive electrode.
BLUE LIGHT?
Therapeutic light that should only be used on bare oily skin; contains few heat rays, is the least penetrating, and has some germicidal and chemical benefits.
CATALYSTS?
Any substances having the power to increase the velocity (speed) of a chemical reaction.
CATAPHORESIS?
Process of forcing acidic substances into deeper tissues using galvanic current from the positive toward the negative pole.
CATHODE?
Negative electrode.
CIRCUIT BREAKER?
Switch that automatically interrupts or shuts off an electric circuit at the first indication of overload.
COMPLETE CIRCUIT?
The path of an electric current from the generating source through the conductors and bak to its original source.
CONDUCTOR?
Any substance, material, or medium that easily transmits electricity.
CONVERTER?
Apparatus that changes direct current to alternating current.
DIRECT CURRENT?
Constant, even-flowing current that travels in one direction only,
DESINCRUSTATION?
Process used to soften and emulsify grease deposits (oil) and blackheads in the hair follicles.
ELECTRIC CURRENT?
Flow of electricity along a conductor.
ELECTRICITY?
Form of energy that when in motion exhibits magnetic, chemical, or thermal effects; a flow of electrons.
ELECTRODE?
Applicator for directing the electric current from the machine to the clients skin.
ELECTROMAGNETIC RADIATION?
Also called radiant energy because it carries, or radiates energy through space on waves.
FUSE?
Special devise that prevents excessive vurrent from passing through a circuit.
GALVANIC CURRENT?
Constant and direct current (DC), having a positive and negative pole and producing chemical changes when it passes through the tissues and fluids of the body.
INACTIVE ELECTRODE?
Opposite pole from the active electrode.
INFRARED RAYS?
Invisible rays that have longer wavelengths, penetrate deeper, and produce more heat that visible light.
INSULATOR or NONCONDUCTOR?
Substance that does not easily transmit electricity.
IONTOPHORESIS?
Process of introducing water-soluble products into the skin with the use of electric current, such as the use of the positive and negative poles of a galvanic machine.
KILOWATT?
1000 watts.
MIILIAMPERE?
One thousandth of an ampere?
MODALITIES?
Currents used in electrical facial and scalp treatments.
OHM?
Unit that measures the resistance of an electric current.
POLARITY?
Negative or positive pole of an electric current.
RECTIFIER?
Apparatus that converts alternating current to direct current.
RED LIGHT?
Therapeutic light used on dry skin in combination with oils and creams;penetrates the deepest and produces the most heat.
TESLA HIGH FREQUENCY CURRENT?
Thermal or heat-producing current with a high rate of oscillation or vibration; also called violet ray.
ULTRAVIOLET (UV) RAYS?
Invisible rays that have short wavelengths, are the least-penetrating rays, produce chemical effects, and kill germs; also called cold rays or actinic rays.
VISIBLE LIGHT?
the primary source of light used in facial and scalp treatments. all the light we can see.
VOLT?
unit that measures the pressure or force that pushes the flow of electrons forward through a conductor.
WALL PLATE?
Instrument that plugs into an ordinary wall outlet and produces various types of electric currents that are used for facial and scalp treatments.
WATT?
Measurement of how much electric energy is being used in one second.
WAVELENGTH?
Distance between successive peaks of electromagnetic waves.
WHITE LIGHT?
Referred to as combination light because it is a combination of all visible rays of the spectrum.
