flow of electricity along a conductor electric current
material that conducts electricity conductor
a material that does not transmit electricity insulator
a path of negative and positive electric currents moving from the generating source thru conductors and back to the source complete electric circuit
constant even-flowing current that travels in one direction dc or direct current
rapid and interrupted current flowing first in one direction and then in opposite direction. ac or alternating current
how fast does electricity travel 186,000 miles per second
unit of measures pressure of electric current volt
unit that measures the strength of an electric current amp
current used for facial and scalp treatments milliampere
unit that measures the resistance of electric current ohm
unit that measures how much electric energy used in 1 second watt
1000 watts kilowatt
a wire that will not carry electrical current passing through will overheat
prevents excessive current from passing thru a circuit fuse
a switch that automatically shuts off an electric cicuit when overloaded circuit breaker
completes an electric circuit and carries the current safely away grounding
avoid contact for you and your client when using electricity water and metal
do not attempt to clean around electric outlets while equipment is plugged in
use only one plug in each outlet
inspect all electrical equipment
what should you do when appliances are not in use disconnect
do not place objects on electrical cords
probe is also known as electrode
an applicator for directing electric current to the client's skin probe
negative or positive pole of electric current polarity
negative electrode cathode
positive electrode anode
constant and direct current having a positive and negative pole that produces chemical changes when it passes through the tissues and fluids of the body galvanic current
2 chemical reactions are possible with galvanic current depending on polarity cataphoresis and anaphoresis
process of infusing water soluble products into the skin with electric current iontophoresis
infusing acidic product into deeper tissues using galvanic current cataphoresis
process of softening and emulsifying grease deposits and blackheads in hair follicles desincrustation
infusing product into the tissues anaphoresis
extremely low level of elctricity that mirrors the body's natural electrical impulses microcurrent
tesla high frequency current also known as violet ray
thermal or heat-producing current with a high rate of oscillation or vibration for scalp and facial treatments Tesla high-frequency
pacemaker,epilepsy,cancer,pregnancy,phlebitis or thrombosis contraindications for electric current
ionic hair dryers combats static electricity and flyaway hair
name given to all forms of energy or radiation that exist electromagnetic spectrum
measurement of the distance between two wavelengths waveform
light at either end of the visible spectrum invisible light
actinic light ultraviolet light
invisible light that has short wavelength is less penetrating and causes chemical reactions and kills germs cold light

longest wavelength of UV light spectrum and damages skin (used in tanning beds) ultraviolet A
produces more heat than visible light infrared light
substances that speed up chemical reactions catalysts
phototherapy or the application of light rays for treatment light therapy
light amplification stimulation emission of radiation Laser
process that turns the light from the laser into heat photothermolysis
