Electricity

Electricity

The movement of particles around an atom that creates energy

Electricity

Creation of energy from the movement of particles around an atom

When in motion, electricity has three effects thermal, magnetic and ---

Chemical

Electric current

The flow of electricity along a conductor

Conductor

Any material that allows electricity to easily flow through it

Silver is an example of a:

Conductor

Another term for a nonconductor

Insulator

Insulator

Materials that prevents the flow of electricity to go through them

Which of the following materials would be a good nonconductor or insulator

Rubber

Certain liquids can be insulators too, such as alcohol, oil and:

Distilled water

Complete Circuit

When electrons flows from the source to a load and back to the source

When you plug in your facial machine, turn it on and use it, you have an example of

Closed Circuit

Direct Current

Flows only in one direction; cellular phones and flashlights use the current

Alternating Current

When electrons flow in one direction and then in the opposite direction

Direct Current

Electrical current has electrons that flow in only one direction, have a constant, even flow and produced by chemical

Convertor

An apparatus that changes direct current (DC) to alternating current (AC)

Volt

The force or pressure of an electrical current passing through a conductor

An Amp or Ampere is a unit that measures the ---- of an electrical current

Strength

Milliampere

Current used for skin treatments

Ohm

Unit of electrical resistance

Watt

Unit that measures how much electric energy is being used

Circuit Breaker

A switch or safety device that will shut off an appliance when there is an over load to the electrical circuit

Electrotherapy

Uses electrical currents that pass through the skin to produce therapeutic effects

Electrode

A conductor used to bring the electric current from the appliance to the client

Wavelengths

The distance between peaks of electromagnetic waves

Electrochemical Effect

When electricity flows through a water-based solution to produce a relaxing or stimulating effect

Pacemakers

A contraindication to using an electric device on a client

Visible Light

The electromagnetic radiation that we can see

Convertor

The apparatus that changes direct current to alternating

Human Body

An example of a good conductor

Light therapy

Exposure to light rays to produce therapeutic effects on a person

Polarity

Indicates the different poles (positive or negative) of an electrical current

Galvanic

The direct current that has a chemical effect on the body

Infrared

Light that produces heat; used in facials or to help aid to processing hair color

Ultraviolet

Light that is less penetrating, produces germicidal effects and has the shortest wavelengths in the light spectrum
