energy
Electricity does not occupy space or have physical or chemical properties; it is, however, a form of:
copper
metal substance, good conductor
complete circuit
The path of an electric current from the generating source through conductors and back to its original source.
insulators
materials that DO NOT allow current to flow through such as rubber, silk, wood, and glass
direct current
even-flowing current that flows in one direction
converter
apparatus that changes direct current to alternating current
alternating current
rapid and interrupted current, flowing first in one direction and then in the opposite direction
volt
unit that measures the pressure or force that pushes the flow of electrons forward through a conductor
rectifier
A device which converts alternating current to direct current and is used to recharge batteries or supply direct current for other purposes.
amp
unit that measures the amount of an electric current
watt
is a measurement of how much electric energy is being used in 1 second.
milliamperes
The current that is used for facial and scalp treatments is measured in
fuse
special device that prevents excessive current from passing through a circuit
electric shock or burn or fire
careless electrical connections and overloaded cirucits cause
live connection
Supplies current to the circuit.
electrotheraphy
electronic facial treatments
electrode
applicator for directing the electric current from machine to clients skin
polarity
indication of negative or positive pole of an electric current
anode
Positive electrode
galvanic current
most used modality
iontophoresis
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
Cataphoresis
Forces acidic substances into deeper tissues using galvanic current from the positive toward the negative pole.
desincrustation
the process of softening and emulsifying oil deposits and blackheads in the follicles is
Telsa current
a thermal or heat producing current with a high rate of oscillation or vibration
infrared rays
what has long wave lengths, penetrates the deepest, and has the most heat
white light
All of the colours of visible light combined
ultraviolet rays
invisible rays that have short wavelengths are the least-penetrating rays, produce chemical effects, and kill germs
wavelength
the distance between identical points on successive waves
load
any electrical appliance activated by the flow of electric current such as a blow dryer
one ampere
is equal to 1000 miliampere
strength
an ampere is a unit of electric
circuit breaker
device breaks the flow of current when an overload occurs
batteries and generators
are common sources of electric current
