Definitions 1
____ is the movement of particles around an atom that creates pure energy.
Electricity
What are the two types of electric currents?
1)Direct Current (DC)
2)Alternating Current (AC)
Is the unit that measures the pressure of force that pushes electric current forward through a conductor.
Volt
Is the positive and the negative pole of an electric current.
*Positive: Anode: Usually red and marked P or +
*Negative: Cathode: Usually black and marked N or -
Polarity
How fast does lightning travel?
Lightning can travel up to speeds of 60,000 miles per hour threw the air.
___ is the flow of electricity along a conductor.
Electric Current
Is a constant even-flowing current that travels in one direction only and is produced by chemical means.
*Flashlights, cell phones, telephones, cordless hairstyling tools.
Direct Current
The measurement of the strength of a electric current
Ampere
Is an applicator for directing electric current from an electrotherapy device to the clients skin.
*Also known as a probe
Electrode
How fast is electricity?
Electricity is very fast: 186,000 miles per second. If you were to travel that fast, you could go around the world eight times in the time it takes you to turn a light on.
Any material that conducts electricity. Meaning that electricity will pass threw the material easily.
*Most metal are good conductors
*Copper is a good conductor
Conductor
Is a rapid and interrupted current, flowing first in one direction then I the opposite direction, it is produced by mechanical means and changes direction 60 times per seconds.
*Corded hair dryers, Curling irons, Table lamps
Alternating Current
The measurement of how much electricity is being used that second.
Watt
Is the light at either end of the visible spectrum of light that is invisible to the naked eye.
Invisible Light
What is it called when electricity is use for skin treatments?
Electrotherapy is when electric currents are used to treat the skin.
Is a material does not transmit electricity. Meaning does not allow electricity to flow threw it.
*Also referred to as an Insulator
Nonconductor
Is an apparatus that changes the direct current to alternating current.
Converter
Is 1,000 watts. In your house it is measured how many kilowatts per hour(kwh).
Kilowatt
Are substances that speed up chemical reactions, some use heat as an energy source while others use light.
Catalyst
What does Laser stand for?
Laser stands for Light Amplification Stimulation Emission of Radiation.
*All lasers work by photothermolysis, a process that turns the light from the laser into heat.
The path of negative and positive electric currents moving from the generating source through the conductors and back to the generating source.
Complete Electric Circuit
Is an apparatus that changes the alternating current to direct current.
Rectifier
It 1/1,000 of a ampere. This is used towards facial and scalp treatments because the ampere is to strong.
Milliampere
Is and application of light rays to the skin for the treatment of wrinkles, capillaries, pigmentation, or hair removal.
*Also known as Phototherapy.
Light Therapy
What company tests all the electrical appliances?
Underwriters Laboratories (UL) certifies the safety of electrical appliances. This certifies that they are safe when used according to manufactures direction.
