is the movement of particles around an atom that creates pure energy.
is the flow of electricity along a conductor.
is any material that conducts electricity
Lightning bolts travel through the air at speeds of up to _________ miles per hour
also knows as insulator is a material that does not transmit electricity.
abbreviated DC, ia a constant, even flowing current that travels in one direction only and is produced by chemical means.
is an apparatus that changes direct current to alternating current.
abbreviated AC, is a rapid interrupted current, flowing first in one direction and then in opposite direction it is produced by mechanical means changes directions 60 times per second.
is an apparatus that changes alternating current AC to direct current DC.
Electricity travels very fast; _________ miles pre second.
abbreviated V and also know as voltage is the unit that measures the pressure or force that pushes electric current forward through a conductor .
abbreviated A and also know as amp; is the unit that measures the strength of an electric current.
abbreviated mA; is 1/100 of an ampere
abbreviated O; is a unit that measures the resistance of an electric current.
abbreviated W, is a unit that measures how much electric energy is being used in one second.
abbreviated K, is 1,000 watts
prevents eccessive current from passing through a circuit.
is a switch that automatically interrupts or shuts off an electric circuit at the first indication of an overload.
completes an electric circuit and carries the current safely away.
underwriters laboratories UL
certifies the safety of electrical appliances.
also know as probe, is an applicator for for directing electric current from electrotherapy.
is the negative or positive pole of an electric current.
the anode is usually red and is marked with a P or a plus (+) sign.
is a constant and direct current having g a positive and negative pole that produces chemical changes when it passes through the tissues and fluids of the body .
is the electrode used on the area to be treated.
is the opposite pole from the active electrode.
is the 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 the galvanic machine.
infuses an acidic positive product into deeper tissues using galvanic current from the positive pole toward the negative pole.
infuses an alkaline negative product into the tissues from the negative pole toward the positive pole.
is a form of anaphoresis and is a process used to soften and emulsify grease deposits and blackheads in the hair follicles.
is an extremely low level of electricity that mirrors the body's natural electrical impulses.
tells high frequency current
also known as violet ray, is a thermal or heat producing current with a high rate of oscillation or vibration that is commonly used for scalp and facial treatments.
the benefits of the tesla high frequency current are
stimulates blood circulation, increases elimination and absorption, increases skin metabolism, improves germicidal action, relieves skin congestion.
complete electric circuit
is the path of negative and positive electric currents moving from the generating source through the conductors and back to the generating source.
also known as electromagnetic spectrum of radiation is the name given to all of the forms of energy that exist.
the distance between two successive peaks of electromagnetic waves.
low frequency, deeper penetration, less energy
high frequency, less penetration, more energy
visible spectrum of light
is the part of the electromagnetic spectrum that can be seen.
is the light at either end of the visible spectrum of light that is invisible to the naked eye.
natural light is made up of three types of light
visible light 35%, Invisible infrared light 60%, invisible ultraviolet light 5%
abbreviated UV light and also known as cold light or actinic light, is invisible light that has a short wavelength giving it a 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 some germs.
ultraviolet A light has the longest wavelength of the UV light spectrum and penetrates directly into the dermis of the skin damaging the collagen and elastin.
light is often called the burning light because it is most associated with sunburns.
is blocked by the ozone layer.
has longer wavelengths penetrates more deeply, has less energy and produces more heat than visible light.
are substances that speed up chemical reactions.
also know as phototherapy is the application of light rays to the skin for the treatment of wrinkles, capillaries, pigmentation, or hair removal.
is an acronym for light amplification stimulation emission of radiation; it is a medical device that uses electromagnetic radiation for hair removal treatments.
a process that turns light from the laser into heat.
light emitting diode
abbreviated led is a medical device used to reduce acne increase skin circulation and improve collagen content in the skin.
a color component within the skin such as blood or melanin.
intense pulse light
is a medical device that uses multiple colors and wavelengths of focused light to treat spider veins, hyper pigmentation, rosacea and redness, wrinkles, enlarged hair follicles and pores, and excessive hair,
blue light 570mm
reduces acne reduces bacteria
red light 640mm
increases circulation improves collagen and elastin production, stimulates wound healing.
yellow light 590mm
reduces swelling and inflammation, improves lymphatic flow, detoxifies and increases circulation.
green light 525mm
reduces hyper-pigmentation, reduces redness, calms and soothes.
