|
Electricity
|
a form of energy that when in motion exhibits magnetic, chemical or thermal effects
|
|
|
Copper
|
is a good conductor
|
|
|
Direct Current
|
is a constant even flowing current that travels in one direction
|
|
|
Alternating Current
|
rapid and interupted current flowing first in one direction, then the opposite. Hair dryers and curling irons that plug into a wall outlet use alternating current
|
|
|
Volt
|
unit that measures the pressure or force that pushes the flow of electrons forward through a conductor
|
|
|
Amp
|
or ampere is the unit that measures the strength of an electric current
|
|
|
Milliampere
|
one thousandth of an ampere-the current used for facial treatments is measured in milliampere
|
|
|
Ohm
|
A unit that measures the resistance of an electric current
|
|
|
Polarity Changer
|
a switch that reverses with the direction of the current from a positive to a negative and vice versa
|
|
|
Fuse
|
a special device that prevents excessive current from passing through a circuit
|
|
|
Circuit Breakers
|
Have replaced fuses in modern electric circuits
|
|
|
All electrical appliances must have
|
at least 2 electrical connections
|
|
|
the ground
|
completes the circuit
|
|
|
a wall plate
|
plugs into an ordinary wall outlet and produces different types of currents called modalities
|
|
|
anode
|
positive electrode-usually red marked P or +
|
|
|
cathode
|
negative electrode usually black marked -
|
|
|
most commonly used modality
|
galvanic current-it is constant & direct
|
|
|
Iontophoresis
|
the process of introducing water soluble products into the skin with the use of electric current such as the positive and negative poles of a galvanic machine
|
|
|
Cataphoresis
|
forces acidic substances deeper into tissues using galvanic current from the positive to negative pole
|
|
|
Anaphoresis
|
process of forcing liquids into tissues from the negative to positive poles
|
|
|
Desincrustation
|
process used to soften and emulsify grease deposits and blackheads in hair follicle
|
|
|
Sinusodial Current
|
used during scapl and facial manipulations, best suited for nervous clients
|
|
|
Tesla High frequency current
|
or zapper-thermal or heat producing current
|
|
|
indirect application
|
client holds the tube electrode
|
|
|
visible light
|
electromagnetic radiation we can see
|
|
|
electro magnetic radiation
|
also called radiant energy
|
|
|
Ultraviolet and infrared rays are invisible because
|
the wavelengths are beyond visible spectrum
|
|
|
invisible rays make up
|
65%
|
|
|
Ultraviolet Rays
|
make up 5% produce chemical effects
|
|
|
infrared rays
|
make up 60% produce most heat
|
