Electricity
|
A form of energy that produces light, magnetic and chemical changes.
|
|
Electric Current
|
The movement of electricity along a path called a conductor.
|
|
Load
|
The technical name for any electrically powered appliance.
|
|
Conductor
|
A material that allows electrically to flow through it easily.
|
|
Insulator
|
A material that does not allow the flow of electric current.
|
|
Amp
|
A unit of electric strength. |
|
Volt
|
A unit of electric pressure. |
|
Ohm
|
A unit of electric resistance.
|
|
Watt
|
A measure of how much electrical energy is being used. |
|
Electrotherapy
|
The application of electrical currents during treatments to the skin. |
|
Direct Current (DC)
|
Current in which electrons move at an even rate and flow in only one direction.
|
|
Alternating Current (AC)
|
Current in which electrons flow first in one direction then in the other. |
|
Battery
|
Have a positive terminal (+) and a negative terminal (-) and produces direct current only. |
|
Generator
|
Produce alternating current.
|
|
Frequency
|
Number of times cycling occurs per second. |
|
Circuit
|
Closed path, through which electrons travel.
|
|
Closed Path
|
A path on which the electrons leave the source and operate an appliance. |
|
Open Circuit
|
Broken path |
|
Overload
|
When more current flows than the line is designed to carry. |
|
Short Circuit
|
Occur any time a "foreign conductor" comes in contact with a wire carrying current to a load. |
|
Fuse
|
A device that contains a fine metal wire that allows current to flow through it.
|
|
Circuit Breaker
|
Simply a reusable device that breaks the flow of current when an overload occurs. |
|
Grounding Wire
|
Designed to protect you when operating certain kinds of appliances. |
|
Local Shock
|
Passes through a small part of the body, causing burns and muscle contractions. |
|
General Shock
|
Passes through the nervous system |
|
Electrochemical Effects |
Created when electric current travels through water-based solution in order to produce relaxing or stimulating results. |
|
Electrotherapy |
The application of special currents that have certain effects on the skin |
|
Galvanic Current |
A direct current of low voltage and high amperage. Has chemical effects that are caused by passing the current through particular acid or alkaline solutions or by passing the current through body tissue and fluids. |
|
Phoresis |
Process of forcing an acid or alkali into the skin by applying current to the chemical . |
|
Anaphoresis |
Use a negative pole or electrode to force negatively charged solutions into the skin without breaking the skin. |
|
Cataphoresis |
Uses a positive pole of electrode to force positively charged solutions into the skin without breaking the skin. |
|
Iontophoresis |
Introduces water-soluble treatment products to the skin. |
|
Faradic Current |
An alternating current, interrupted to produce a mechanical, non chemical reaction. It also stimulates the nerve and muscle tissue. |
|
Sinusoidal Current |
An alternating current with a mechanical effect, like the Faradic current that produces muscle contractions. |
|
Tesla Current |
Known as the "violet ray" it is a alternating current. It can be adjusted to different voltages to produce heat. |
|
Light Therapy |
Th production of beneficial effects such as reducing acne through treatments using light rays or waves. |
|
Visible Light |
The portion of the electromagnetic spectrums humans can see. |
|
Fluorescent Light |
Economical and long-lasting light source. It can create blue or cool tones. |
|
Incandescent Light |
It is ordinary light bulb. Produces redder tones or warmer casts. Closer to natural sunlight. |
|
Infrared Light |
Produce pure heat rays. It increases circulation and skin gland secretions. It also relaxes muscles and stimulates the cell and tissue activity. |
|
Ultraviolet Light |
Known as actinic rays. They have shorter wavelength and can be more damaging than the infrared rays. It produces both a positive and negative effects on the skin depending on the exposure time. It also can kill bacteria that causes skin infections. |
