Milady Standard Ch.13 Basics of Electricity Review

Amp

Unit of measurements for the amount of current running through a wire

Volt

Unit of measuring the pressure that forces the electric current forward

Milliampere

One-thousandth of an ampere

Ohm

This unit of measures the resistance of an electric current

Watt

Measurement of how much electric energy is being used in one second

Kilowatt

The electricity in your house is measured in this manner

Alternating Current

a rapid and interrupted current, flowing first in one direction and then in the opposite direction

Electric current

the flow of electricity along a conductor

Conductor

any substance that conducts electricity

Fuse

A special device that prevents excessive current from passing through a circuit

Insulator

nonconductor-a substance that does not easily transmit electricity

Electrode

an applicator for directing the electric current from the machine to the clients skin

polarity

indicates the negative and positive pole of an electric current

anode

the positive electrode

cathode

negative electrode

modalities

the four main ones are galvanic, faradic, sinusoidal, and telsa high frequency

galvanic

a constant and direct current, producing chemical changes when it passes through the tissues and fluids of the body

iontophoresis

the process of introducing water-soluble products into the skin with the use of electric current

cataphoresis

forces acidic substances into deeper tissues using galvanic current

anaphoresis

the process or forcing liquids into the tissues from negative toward the positive poles.

disincrustation

the process used to soften and emulsify grease deposits and blackheads in the hair follicles

electricity

a form of energy that produces magnetic, chemical, and thermal effects

converter

is used to change direct current into alternating currents

rectifier

is used to change alternating currents into direct currents

telsa high-frequency current

a thermal or heat-producing current with a high rate of oscillation or vibration

direct current

current that is constant, even-flowing current traveling in one direction

infrared rays

make up 60% of natural sunlight

microcurrent

an extremely low level of electricity that mirrors the body's natural electrical impulses

wavelength

distance between successive peaks of electromagnetic waves

waveform

measurements of the distance between two wavelengths

light-emitting diode

abbreviated LED, a medical device used to reduce acne, increases skin circulation, and improve the collagen content in the skin

catalysts

substances that speed up chemical reactions

chromophore

a color component within the skin such as blood or melanin

circuit breaker

switch that automatically interrupts or shuts off an electric circuit at the first indication of overload
