Milady's Basics Of Electricity Chp. 11
Electric Current
A flow of electricity along a conductor.
Electricity
A form of energy that produces magnetic, chemical, and thermal effects.
Complete Circuit
A path of an electric current from the generating source through conductors and back to its original source
Insulator or Nonconductor
A substance that does not easily transmit electricity.
Conductor
A substance that permits electrical current to pass through it; any substance that transmits electricity.
Rectifier
An apparatus that changes alternating current to direct current.
Converter
Apparatus that changes direct current to alternating current.
Polarity
Indicates the negative or positive pole of an electric current
Galvanic Current
Most commonly used modality; constant and direct current (DC), having a positive and negative pole and producing chemical changes when it passes through the tissues and fluids of the body
Cathode
Negative electrode
Anaphoresis
process of forcing liquids into the tissues from the negative toward the positive pole
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
Desincrustation
process used to soften and emulsify grease deposits and backheads in the hair follicles
Fuse
special device that prevents excessive current from passing through a circuit
Circuit Breaker
switch that automatically interrupts or shuts off an electric circuit at the first indication of overload
Inactive Electrode
the opposite pole from the active electrode.
Visible Light
the primary source of light used in facial and scalp treatments
Blue Light
theraputic light that should only be used on bare oily skin; contains few heat rays, is the least penetrating and has some germicidal and chemical benefits
Telsa High Frequency
thermal or heat producing current with a high rate of oscillation or vibration;also called violet ray
Ohm (O)
unit that measures the resistance of an electrical current.
Infrared Rays
make up 60 percent of natural sunlight.
Ultraviolet (UV) Rays
makes up 5% of natural sunlight
Watt (W)
measurement of how much electric energy is being used in one second.
White Light
mixture of all the colors in the visible spectrum
Milliampere
one thousandth of an ampere
Kilowatt (K)
1,000 watts
Direct Current (DC)
Constant, even-flowing current that travels in one direction only.
Two types of electric current
Direct (DC) and Alternating (AC)
Electromagnetic Radiation
Energy that is transferred by electromagnetic waves. Visible light that we can see
Cataphoresis
Forces acidic substances into deeper tissues using galvanic current from the positive toward the negative pole.
Anode
Positive electrode
Alternating Current (AC)
Rapid and interrupted current, flowing first in one direction and then in the opposite direction
Wavelength
The distance between corresponding points on adjacent waves
Red Light
Theraputic light used on dry skin types in combination with oils & creams; penetrates the deepest & produces the most heat
Amp (A)
Unit that measures the amount of an electric current.
Volt (V)
Unit that measures the pressure or force that pushes the flow of electrons forward through a conductor.
Catalysts
Used to make reactions happen more quickly.
Four main types of electrical measurements
Voltage, Amp, Ohm and Watt
Electrode
applicator for directing the electric current from machine to clients skin
Modalities
currents used in electrical facial and scalp treatments
Active Electrode
electrode used on the area to be treated
Wall Plate
instrument that plugs into an ordinary wall outlet and produces various types of electric currents that are used for facial and scalp treatments
