Ch. 9 Electricity and Light Therapy

alternating current (AC) rapid and interrupted current, flowing in one direction then the opposite direction
amp (ampere) standard unit for measuring the strength of an electric current or the rate of flow of charge in a conductor
anaphoresis process of forcing substances into tissues using galvanic current from the negative towards the positive pole
anode positive electrode
cataphoresis process of forcing acidic substances into tissues using galvanic current from the positive pole towards the negative pole
cathode negative electrode
circuit breaker switch that automatically interrupts or shuts off an electric circuit at the first sign of overload
complete circuit the path of an electric current from the generating source through the conductor and back to its original source
conductor any substance, medium, or material that conducts electricity
converter an apparatus that changes direct current to alternating current
desincrustation process used to soften and emulsify oil and blackheads in the hair follicles
direct current (DC) constant current that travels in one direction only and produces a chemical reaction
electric current the flow of electricity along a conductor
electrode an applicator used to direct electric current from a machine to the skin
electrotherapy electronic scalp and facial treatment
faradic current alternating current that produces a mechanical reaction without chemical effect
fuse device that prevents excessive current from passing through a curcuit
galvanic current constant and direct current, having a positive and negative pole, that produces chemical changes in tissues and body fluids
ground fault circuit interrupter a device that senses imbalances in an electric current
infrared rays invisible rays with long wavelengths and deep penetration; produce the most heat of any therapeutic light
insulator substance that does not easily transfer electricity
iontophoresis process of introducing water-soluble products into skin through use of electric current
modalities currents used in electric facial and scalp treatments
ohm (O) the unit if electrical resistance in an electric current
polarity negative or positive pole of an electric current
rectifier apparatus that changes alternating current to direct current
rheostat an adjustable resistor used for controlling current in a circuit
sinusodial current alternating current used in scalp and facial manipulations that produces mechanical contractions
Tesla high-frequency current thermal or heat producing current with a high oscillation rate; also known as the violet ray
ultraviolet light invisible rays, with short wavelengths and minimal skin penetration, that produce chemical effects and kill germs; also called actinic or cold rays
visible light electromagnetic radiation that can be seen by the human eye
volt (V) a unit of electrical pressure that pushes the flow of electrons forward through a conductor
watt (W) the unit of power (amperes multiplied by volts) indicating how much electric energy is being used in one second
wavelength distance between rwo successive peaks of electromatic waves
