Electricity & Electrical Safety

Question 1

Electricity

Answer 1

is the movement of electrons from one atom to another along a conductor. Electricity

Question 2

electric current

Answer 2

is the flow of electricity along a conductor.

Question 3

is the flow of electricity along a conductor.

Answer 3

is any material that conducts electricity.

Question 4

nonconductor

Answer 4

(also known as an insulator) is a material that does not transmit electricity.

Question 5

complete electric circuit

Answer 5

is the path that negative and positive electric currents take from the generating source through the conductors and back to the generating source.

Question 6

Direct current

Answer 6

(DC) is a constant, even-flowing current that travels in one direction only and is produced by chemical means.

Question 7

inverter

Answer 7

is an apparatus that changes direct current to alternating current. I

Question 8

Alternating current

Answer 8

AC, is a rapid and interrupted current, flowing first in one direction and then in the opposite direction; it is produced by mechanical means and changes directions 60 times per second.

Question 9

rectifier

Answer 9

is an apparatus that changes alternating current to direct current.

Question 10

volt

Answer 10

abbreviated as V and also known as voltage is the unit that measures the pressure or force that pushes electric current forward through a conductor

Question 11

ampere

Answer 11

abbreviated as A and also known as amp (AMP), is the unit that measures the strength of an electric current.

Question 12

milliampere

Answer 12

abbreviated as mA, is 1⁄1,000 of an ampere. The current used for facial and scalp treatments is measured in milliamperes;

Question 13

ohm

Answer 13

(OHM), abbreviated as O, is a unit that measures the resistance of an electric current.

Question 14

watt

Answer 14

(WAHT), abbreviated as W, is a unit that measures how much electric energy is being used in one second.

Question 15

fuse

Answer 15

prevents excessive current from passing through a circuit.

Question 16

circuit breaker

Answer 16

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

Question 17

Grounding

Answer 17

completes an electric circuit and carries the current safely away

Question 18

polarity

Answer 18

refers to the poles of an electric current, either positive or negative.

Question 19

ground fault interrupter

Answer 19

is designed to protect from electrical shock by interrupting a household circuit when there is a leak in the circuit.

Question 20

anode

Answer 20

the anode is usually red and is marked with a P or a plus (+) sign.

Question 21

cathode

Answer 21

it is usually black and is marked with an N or minus (-) sign

Question 22

galvanic current

Answer 22

is a constant and direct current, having a positive and negative pole, that produces chemical changes when it passes through the tissues and fluids of the body.

Question 23

active electode

Answer 23

is the electrode used on the area to be treated.

Question 24

inactive electrode

Answer 24

is the opposite pole from the active electrode.

Question 25

Iontophoresis

Answer 25

is the process of infusing 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.

Question 26

Cataphoresis

Answer 26

infuses an acidic (positive) product into deeper tissues, using galvanic current from the positive pole toward the negative pole.

Question 27

Anaphoresis

Answer 27

infuses an alkaline (negative) product into the tissues from the negative pole toward the positive pole.

Question 28

desincrustation

Answer 28

, a form of anaphoresis, is a process used to soften and emulsify grease deposits (oil) and blackheads in the hair follicles.

Question 29

Microcurrent

Answer 29

is an extremely low level of electricity that mirrors the body’s natural electrical impulses.

Question 30

ultraviolet (UVA)

Answer 30

Ultraviolet A light has the longest wavelength of the UV light spectrum and penetrates directly into the dermis of the skin, damaging the collagen and elastin. UVA light is the light that is often used in tanning beds.

Question 31

ultraviloet B (UVB)

Answer 31

Ultraviolet B light is often called the burning light because it is most associated with sunburns. Excessive use of both UVA and UVB light can cause skin cancers.

Question 32

Ultraviolet C (UVC)

Answer 32

Ultraviolet C light is blocked by the ozone layer. If the Earth loses its protective layer of ozone, life as we know it will no longer exist. UVC is effective at killing bacteria, viruses, mold and other pathogens.

Question 33

Catalysts

Answer 33

is an extremely low level of electricity that mirrors the body’s natural electrical impulses.
