negative electrode of an electrotherapy device; the cathode is usually black and is marked with an N or a minus (−) sign
What is a cathode?
completes an electric circuit and carries the current safely away
What is grounding?
opposite pole from the active electrode
What is an inactive electrode?
flow of electricity along a conductor
What is electric current?
invisible light with longer wavelengths, deeper penetration, less energy, and more heat production than visible light; makes up 60 percent of natural sunlight
What is infrared light?
process of infusing an alkaline (negative) product into the tissues from the negative pole toward the positive pole
What is anaphoresis?
apparatus that changes direct current to alternating current
what is inverter?
electrode of an electrotherapy device that is used on the area to be treated
What is a active electrode?
measurement of the distance between two wavelengths
What is a wavelength?
the part of the electromagnetic spectrum that can be seen; visible light makes up only 35 percent of natural sunlight
What is visable light?
process of infusing 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
What is iontophoresis?
prevents excessive current from passing through a circui
What is a fuse?
use of electrical currents to treat the skin
What is electrotherapy?
abbreviated as AC; rapid and interrupted current, flowing first in one direction and then in the opposite direction; produced by mechanical means and changes directions 60 times per second
What is alternating current?
abbreviated as UV light and also known as cold light or actinic light; invisible light that has a short wavelength (giving it higher energy), is less penetrating than visible light, causes chemical reactions to happen more quickly than visible light, produces less heat than visible light, and kills germs
Ultraviolet light?
substances that speed up chemical reactions
What is catalysts?
also known as insulator; a material that does not transmit electricity
nonconductor
also known as probe; applicator for directing electric current from an electrotherapy device to the client’s skin
What is an electrode?
abbreviated DC; constant, even-flowing current that travels in one direction only and is produced by chemical means
What Is a direct current?
light at either end of the visible spectrum of light that is invisible to the naked eye
What is invisible light?
also known as electromagnetic spectrum of radiation; name given to all of the forms of energy (or radiation) that exist
electromagnetic spectrum
also known as violet ray; thermal or heat-producing current with a high rate of oscillation or vibration that is commonly used for scalp and facial treatments
Tesla high-frequency current
positive electrode of an electrotherapy device; the anode is usually red and is marked with a P or a plus (+) sign
What is an anode?
positive or negative poles of an electric current
What is polarity?
also known as phototherapy; the application of light rays to the skin for the treatment of wrinkles, capillaries, pigmentation, or hair removal
What is light therapy?
