Electricity & Safety in Beauty: Electrical Theory, Modalities, and Light Energy

What is electricity?

Electricity is a form of energy resulting from the flow of electric charge.

What are the two types of electric current?

Direct current (DC) and alternating current (AC).

What is a conductor?

A material that allows electric current to flow through it.

What is a nonconductor?

A material that does not allow electric current to flow through it.

What is a complete electric circuit?

A closed loop that allows current to flow from a power source to a device and back.

What is a volt (V)?

A unit of electric potential or electromotive force.

What is an ampere (A)?

A unit of electric current.

What is a milliampere (mA)?

One-thousandth of an ampere.

What is an ohm (Ω)?

A unit of electrical resistance.

What is a watt (W)?

A unit of power equal to one joule per second.

What is a kilowatt (kW)?

One thousand watts.

What is a fuse?

A safety device that protects an electrical circuit by melting and breaking the circuit when excessive current flows.

What is a circuit breaker?

A safety device that automatically interrupts the flow of electricity in a circuit when it detects an overload.

What is grounding?

The process of transferring the immediate discharge of electrical energy to the ground.

What is a ground fault interrupter (GFI)?

A device that cuts off electrical power when it detects an imbalance in the electrical current.

What does Underwriters Laboratories (UL) certification indicate?

That the product has been tested for safety and meets specific safety standards.

What should you do if you experience a light electrical shock?

Seek medical attention if necessary and avoid touching water or metal objects.

What are the three electric modalities used in beauty and wellness services?

Galvanic current, microcurrent, and Tesla high-frequency current.

What is galvanic current used for?

It is used for iontophoresis, cataphoresis, and desincrustation.

What is microcurrent used for?

It is used for firming, toning, soothing skin, and healing inflamed tissue.

What does Tesla high-frequency current do?

Stimulates blood circulation, increases skin metabolism, and improves germicidal action.

What is the visible spectrum of light?

The portion of the electromagnetic spectrum that is visible to the human eye.

What is ultraviolet light?

A type of invisible light that can be divided into UVA, UVB, and UVC rays.

What is infrared light used for?

It diminishes signs of aging, heals wounds, increases circulation, and aids in relaxation.

What is one guideline for the safe use of electrical equipment?

Never tamper with appliances.

What should you do with unused appliances?

Disconnect them from the power source.

What is the purpose of inspecting electrical equipment?

To ensure safety and proper functioning.
