Question | Answer |
---|---|
Electrode used on the area to be treated. | active electrode |
Rapid and interrupted current, flowing first in one direction and then in the opposite direction. | alternating current (AC) |
Unit that measures the amount of an electric current | amp |
Process of forcing liquids into the tissues from the negative toward the positive pole. | anaphoresis |
Positive electrode | anode |
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. | blue light |
Any substances having the power to increase the velocity(speed) of a chemical reaction. | catalysts |
Process of forcing acidic substances into deeper tissues using galvanic current from the positive toward the negative pole. | cataphoresis |
Negative electrode | cathode |
Switch that automatically interrupts or shuts off an electric circuit at the first indication of overload. | circuit breaker |
The path of electric current from the generating source through conductors and back to its original source. | complete circuit |
Any substance, material, or medium that easily transmits electricity | conductor |
Apparatus that changes direct current to alternating current. | converter |
Constant, even-flowing current that travels in one direction only. | direct current (DC) |
Process used to soften and emulsify grease deposits and blackheads in the hair follicles. | desincrustination |
Flow of electricity along a conductor. | electric current |
Form of energy that, when in motion, exhibits magnetic, chemical, or thermal effects; a flow of electrons. | electricity |
Applicator for directing the electric current from machine to clients skin. | electrode |
Also called radiant energy becasue it carries, or radiates, energy through space on waves. | electromagnetic radiation |
Special device that prevents excessive current from passing through a circuit. | fuse |
Constant and direct current, having a positive and negative pole and producing chemical changes when it passes through the tissues and fluids of the body. | galvanic current |
Opposite pole from the active electrode. | inactive electrode |
Invisble rays that have longer wavelengths, penetrate deeper, and produce more heat than visible light. | infrared rays |
Substance that does not easily transmit electricity | insulator or nonconductor |
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. | iontophoresis |
1,000 watts. | kilowatt |
One- thousandth of an ampere. | milliampere |
Currents used in electrical facial and scalp treatments. | modalities |
Unit that measures the resistance of an electric current. | ohm |
Negative and positive pole of an electric current. | polarity |
Apparatus that converts alternating current to direct current. | rectifier |
Therapeutic light used on dry skin in combination with oils and creams, penetrates the deepest and produces the most heat. | red light |
Thermal or heat producing current with a high rate of oscillation or vibration; also called violet ray. | Telsa high frequency current |
Invisible rays that have short wavelengths, are the least penetrating rays, produce chemical effects and kill germs; also called cold rays or actinic rays. | ultraviolet (UV) rays |
The primary source of light used in facial and scalp treatments. | visible light |
Unit that measures the pressure or force that pushes the flow of electrons forward through a conductor. | volt |
Instrument that plugs into an ordinary wall outlet and produces various types of electric currents that are used for facial and scalp treatments. | wall plate |
Measurement of how much electric energy is being used in one second. | watt |
Distance between successive peaks of electromagnetic waves. | wavelength |
Referred to as combination light because it is a combination of all visible rays of the spectrum. | white light |
