False
Electricity does not occupy space or have physical or chemical properties
True
There are two types of electric current direct and converted
False
Normal electric wall sockets that power a hairdryer or curling iron or 220 V
False
The heating element in a hairdryer heats up because it is not large enough to carry the electric current

A wallplate is also known as a facial stimulator
True
Microcurrent travels throughout the entire body
False
UV props the scan to produce vitamin D, A fat soluble vitamin that promotes mineralization of bones
True
Ultraviolet a light has the longest wavelength of that UV light spectrum
True
Electricity is a form of energy that,when in motion, exhibits
Thermal effects
magnetic affects
chemical effects
Lightning bolts travel through the air at speeds of up to how many miles per hour?
60,000
A substance that is a particularly good conductor of electricity is
Copper
The path of an electric current from that generating source back to the original source is a
Complete circuit
Rubber, silk, wood, and glass are all good examples of
Insulators
Rapid and interrupted current that flows in one direction and then in the opposite direction is
Alternating current
Electricity travels how many miles per second
186,000
The unit that measures the pressure or force that pushes the flow of electrons forward through a conductor is a
Volt
The current for facial and scout treatments is measured in
Milliamperes
A measurement of how much electricity is being used in one second is a
Watt
The special device that prevents excessive current from passing through a circuit is a
Fuse
The electrical appliance connection that supplies current to the circuit is the
Live connection
Electronic facial treatments are commonly referred to as
Electrotherapy
An applicator that directs electric current from a machine to the client skin is
Electrode
The negative or positive pole of an electric current is referred to as the
Polarity
Electronic facial treatments are commonly referred to as
Electrotherapy
The positive electrode is called an
Anode
Infusing water-soluble products into the skin with the use of electric current is known as
Iontophoresis
The process used to treat acne and Milia and soften and emulsify deposits in the hair follicles is
Desincrustation
Cat aphorisms forces acidic substances into deeper tissues using galvanic current from the
Positive to the negative pole
Thermal or heat producing current with a high rate of oscillation or vibration is
Violet ray
The type of current that should not be used on clients who are pregnant have high blood pressure or a pacemaker is
Tesla high-frequency
The distance between two successive peaks is called
Wavelength
Race with short wavelengths that are the least penetrating produce chemicals a fax and kill germs are
Blue light
Rays with long wavelengths that penetrate more deeply and produce more heat than visible light are
Infrared rays
Lasers work by a process that turns the light from the laser into heat called
Photothermolysis
Substances that speed up chemical reactions
Catalysts
Unit that measures the strength of an electric current
Ampere
Unit that measures the resistance of an electric current
Ohm
Current used an electrical facial and scalp
Modalities
Extremely low level of electricity that mirrors the body’s natural electrical impulses
Microcurrent
Color component within the scan such as blood or melanin
Chromophore
An applicator for directing the electric from the machine to the client skin
Electrode
Indicates the negative or positive pole of an electric current
Polarity
The positive electrode
Anode
The negative electrode
Cathode
The four main ones are galvanic, faradic, sinusoidal, and Tesla high-frequency
Modalities
A constant direct-current producing chemical changes when it passes through the tissues and fluids of the body
Galvanic
Forces acidic substances into deeper tissue using galvanic current
Cataphoresis
The process of introducing water-soluble products into the skin with the use of electric current
Iontophoresis
The process of forcing liquids into the tissues from the negative toward the positive poles
Anaphoresis
Hey process used to soften and emulsify grease deposits and blackheads
Desincrustation
Measurement of how much electric energy is being used in one second
Watt
One-thousandth of an ampere
Milliamperes
The unit of measurement for the amount of current running through a wire
Amp
Unit for measuring the pressure that forces the electric current forward
Volt
Electricity in your house is measured in this manner
Kilowatt
This unit measures the resistance of an electric current
Ohm
