The Tesla high-frequency current

(TES-luh _ Hy-FREE-kwen-see _ KuR-ent), also known as violet ray, is a thermal or heat-producing current with a high rate of oscillation or vibration that is commonly used for scalp and facial treatments. Tesla current does not produce muscle contractions, and the effects can be either stimulating or soothing, depending on the method of application. The electrodes are made from either glass or metal, and only one electrode is used to perform a service The benefits of the Tesla high-frequency current are:

• Stimulates blood circulation

            • Increases elimination and absorption

• Increases skin metabolism

• Improves germicidal action

• Relieves skin congestion

As you learn more about facials and treatments, you will become familiar with the term contraindication, a condition that requires avoiding certain treatments, procedures, or products to prevent undesirable side effects.

PER SECOND

A watt (WAHT), abbreviated W, is a unit that measures how much electric energy is being used in one second. A 40-watt light bulb uses 40 watts of energy per second.

209) Electrical current is defined as:

A) The movement of electrons along a path known as an insulator

B) The movement of protrons along a path known as an insulator

C) The movement of neutrons along a path known as an condutor

D) The movement of electrons along a path known as an conductor

The movement of electrons along a path known as an conductor

An electric current (ee-lEK-trik KuR-unt) is the flow of electricity along a conductor. All materials can be classified as conductors or nonconductors (insulators), depending on the ease with which an electric current can be transmitted through them. A conductor (kahn-DuK-tur) is any material that conducts electricity. Most metals are good conductors. This means that electricity will pass through the material easily. Copper is a particularly good conductor and is used in electric wiring and electric motors. Pure (distilled) water is a poor conductor, but the ions usually found in ordinary water, such as tap water or a river or a lake, make it a good conductor. This explains why you should not swim in a lake during an electrical storm

245) An electrical measurement used in measuring Resistance:

A) Amps

B) Ohms

C) Watts

D) Volts

OHMS

An ohm (OHM), abbreviated O, is a unit that measures the resistance of an electric current. Current will not flow through a conductor unless the force (volts) is stronger than the resistance (ohms).

246) In electrical measurement, AMPS measure:

A) Pressure

B) Strength

C) Resistance

D) Energy used per second

STRENGHT

An ampere (AM-Peer), abbreviated A and also known as amp (AMP), is the unit that measures the strength of an electric current. Just as the sink hose must be large enough to carry the amount of water flowing through it, a wire also must be large enough to carry the amount of electricity (AMPs) flowing through it. A hair dryer rated at 12 amPs must have a cord that is twice as thick as one rated at 6 amps; otherwise, the cord might overheat and start a fire. A higher amp rating indicates a greater number of electrons and a stronger current 

247) In electrical measurement, Volts measure:

A) Pressure

B) Strength

C) Resistance

D) Energy used per second

PRESSURE

A volt (VOlT), abbreviated V and also known as voltage (VOl-tij), is the unit that measures the pressure or force that pushes electric current forward through a conductor . Car batteries are 12 volts. Normal electric wall sockets that power your hair dryer and curling iron are 120 volts. Most air conditioners and clothes dryers run on 220 volts. A higher voltage indicates more power.

248) In electrical measurement, Watts measure:

A) Pressure

RECTIFIER

A rectifier (REK-ti-fy-ur) is an apparatus that changes alternating current (AC) to direct current (DC). Cordless electric clippers and mobile phone chargers use a rectifier to change the AC from an electric wall outlet to the DC needed to recharge their batteries. 

There are two types of electric current:

Direct current (dy-REKT _  KUR-unt), abbreviated DC, is a constant, even-flowing current that travels in one direction only and is produced by chemical means. Flashlights, mobile telephones, and cordless hairstyling tools use the direct current produced by batteries. The battery in your car stores electric energy. Without it, your car would not start in the morning. A converter (kun-VUR-tur) is an apparatus that changes direct current to alternating current. 

Converters usually have a plug and a cord. They allow you to use appliances outside of the salon or your home that normally would have to be plugged into an electric wall outlet. The mobile phone charger in a car is an example of a converter

Alternating current (AWL-tur-nayt-ing _ KUR-rent), abbreviated AC, 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. Corded hair dryers, curling irons, electric files, and table lamps that plug into a wall outlet use alternating current.
