salon fundamentals cosmetology chapter 4

the movement of electicity along a conductor is called

electric current

which type of light can create blue or cool tones

fluorescent

what's the type of current that has an electrochemical effect

galvanic

the oldest form of electrotherapy in the salon is

galvanic current

what type of shock passes through the nervous system

general

the power source used most often in a salon is a

generator

a special wire used on some appliances for conducting high and sudden flows of electric current out of the appliance is called a

grounding wire

a benefit of tesla therapy may include

improved blood circulation

what's the technical name for any electrically powered appliance

load

a volt is a unit of electric

pressure

curling irons and heat lamps are examples of which type of electrically powered equipment

thermal

what type of light carries the most energy

ultraviolet

the measure of how much electrical energy is being used is called a

watt

the maximum amount of current used in a galvanic treatment shouldn't exceed

1 milliampere

the very minimum ampere rating of a circuit operating a single 1,000 watt blow dryer would be

10 amperes

tesla treatments should be limited to no more than how many minutes in duration

5 minutes

electric current that flows first in one direction and then the other is called

alternating current

which process uses a negative pole or electrode to force negatively charged solutions into the skin without breaking the skin

anaphoresis

which process uses the positive electrode to force acidic solutions into the skin without breaking the skin

cataphoresis

a closed path through which electrons travel is referred to as a

circuit

what's a device used to protect a circuit from being overloaded

circuit breaker

since silver and copper transport electricity easily, they're called

conductors

what changes direct current into alternating current

converter

a constant electrical current flowing in one direction is called

direct current

light, heat, chemical and magnetic charges are all produced by

electricity

when performing an electrotherapy procedure, what apparatus or current conductor is used to bring the current from the appliance to the clients skin

electrode

the application of special electric currents that have certain effects on the skin are known as

electrotherapy

what's the name of a device with a fine metal wire running through it which will melt and open the circuit if too much current is flowing through it

fuse

what's an example of low voltage direct current and high amps

galvanic

what benefits are believed to be derived through application of the high frequency current

improved blood circulation, increased rate of metabolism, increased sebaceous glandular activity

what light creates the closest substitute for natural sunlight

incandescent

what are the benefits of using infrared light during a facial

increased circulation, relaxation of muscles, increased skin gland secretions

what would be used during a faradic current treatment

indirect method

materials such as glass, rubber or paper that don't allow electricity to flow through them are called

insulators

what process can use either the negative or positive pole to introduce water soluble treatment products to the skin

iontophersis

using electric clippers in cosmetology work would be an example of which kind of electrical effect

mechanical

what materials allow current to pass through them

metal, water, carbon

a unit of electrical resistance is called an

ohm

if appliances are causing more current to flow than what the circuit is designed to carry, what could occur

overloading

what does local shock do

passes through a small part of the body

white light can be broken down into its individual wavelengths by the use of a

prism

what are the temporary effects of the positive pole of galvanic current

produces an acidic reaction, soothes nerves, slows blood flow by contracting the vessels

what's true about a positive pole of galvanic current

produces an acidic reaction, soothes nerves, slows blood flow by contracting the vessels

the chemical breakdown of the skin caused by intense heat is called

pyrolysis

what changes alternating current into direct current

rectifier

the measure of how difficult it is to push electrons through a conductor is called

resistance

dropping an electrical appliance into water is an example of

short circuit

what's true about the anode

shows a large p, usually colored red, shows a positive sign

what type of electrotherapy current is considered superior to faradic current therapy because it penetrates more deeply

sinusoidal

what's true about cataphoresis

slows the flow of blood, soothes nerves, decreases redness of simple blemishes

an ampere is a unit of electric

strength

high frequency and alternating current are characteristics of which type of electrotherapy

tesla

what would be an example of closing a circuit

turning on a light switch

bacteria that cause skin infections can be killed by which kind of light

ultraviolet

what type of light has the shortest wavelength

ultraviolet

which steps would be followed to break the circuit when a person comes into contact with an electric current

unplug appliance, turn off all the circuit breakers, knock the person out of the circuit using an insulator

what methods are recommended for extinguishing an electrical fire

use a fire extinguisher, smother it with a towel, pour corn starch on it

the portion of the electromagnetic spectrum that humans can see is called

visible light

small doses of ultraviolet light may help the body produce

vitamin d

in order to apply special currents to the skin, what device is used to reduce the current from a typical 120 volt power source to a level safely handled by the human body

wall plate
