Electricity

Electrical Theory

100

This is a constant, even flowing current that travels as one direction only and is produced by chemical means. i.e batteries

Direct Current

200

This 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.

Alternating current

300

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

Rectifier

400

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

Inverter

500

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

Complete electric circuit

Electrical Measurements

100

This is the unit that measures the pressure or force that pushes electric current forward through a conductor.

Volt

200

This is the unit that measures the strength of an electric current. 

Ampere

300

This current is used for facial and scalp treatments, and is 1/1,000 of an ampere.

Milliampere

400

This is the unit that measures the resistance of an electric current. 

Ohm

500

This unit measures how much electric energy is used in one second. 

Watt

Safety Devices

100

This prevents excessive current from passing through a circuit.

Fuse

200

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

Circuit breaker

300

This completes an electric circuit and carries the current safely away.

Grounding

400

This label certifies the safety of electrical appliances.

Underwriters Laboratories (UL)

500

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

Ground fault interrupter

Electrotherapy Modalities

100

This refers to the use of electrical currents to treat the skin.

Electrotherapy 

200

This 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.

Galvanic 

300

Stimulating and irritating the nerves is a result of this.

Anaphoresis

400

Improvement of germicidal action is a result of this. 

Tesla high frequency

500

Also known as a probe, this is the applicator for directing electric current from an electrotherapy device to the clients skin. 

Electrode

Light Energy

100

This is invisible light that has a short wavelength, less penetrating than visible light, produces less heat than visible light and kills some germs. 

Ultraviolet Light

200

This has longer wavelengths, penetrates more deeply, has less energy and produces more heat than visible light. This makes up 60% of natural sunlight.

Infrared light

300

This is the application of light rays to the skin for treatment of wrinkles, capillaries, pigmentation or hair removal.

Light therapy

400

These are substances that speed up chemical reactions. 

Catalysts

500

These lights may be cooler (green/blue) than natural sunlight. Your clients hair, skin, and nails will appear more green-blue when viewed with this lighting. 

Fluorescent light
