energy
Electricity is described as a form of:
electric current
The flow of electricity along a conductor is called a(n)
conductors
Metals used in electric wiring and motors are materials that are considered good electricity:
nonconductor
Electric wires are usually covered with a rubber substance that is used as an insulator or:
complete circuit
The path of electricity from the generating source through conductors and back to the original source is called a(n)
direct current
Electric current that is constant, even-flowing and travels in one direction is:
converter
The device that changes direct current to alternating current is a(n)
alternating current
A rapid and interrupted current that flows in one direction then in the opposite direction is :
volt
The unit that measures the pressure or force that pushes the flow of electrons through a conductor is a (n)
ampere
The unit that measures the amount of electric current is a(n)
milliamperes
The current that is used for facial and scalp treatments is measured in :
watt
The unit that measures how much electric energy is being used in one second is a (n)
fuse
The device that prevents excessive current from passing through a circuit is a (n)
circuit breaker
A switch that automatically interrupts or shuts off an electric current at the first indication of an overload is a (n)
grounding
An important way of promoting electrical safety is the principle of:
electrode
An applicator that is used for directing the electric current from the machine to the clients skin is called a (n)
anode
The positive electrode of an electrotherapy device is called a (n):
cathode
The negative electrode of an electrotherapy device is called a (n)
galvanic current
The most commonly used modality that is a constant and direct current is:
iontophoresis
The process of forcing water-soluble products into the skin with the use of electric current is called :
anaphoresis
A process that forces liquids into the tissuse from the negative toward the positive pole is called:
Tesla current
A thermal or heat-producing current with a high rate of oscillation that is used for scalp and facial treatments is :
35 percent
Visible light, the part of the electromagnetic radiation spectrum that we can see, makes up what percentage of natural sunlight ?
infrared rays
The long wavelenghts that penetrate the deepest and produce the most heat are:
safety goggles
To avoid damage to the eyes of a client or practitioner when using light therapy treatments, the eyes should be protected with saturated cotton pads or:
Cataphoresis
forces acidic substances into deeper tissue using galvanic current from the positive toward the negative pole
Most commonly used modality is
galvanic current
polarity
indicates the negative or positive pole of an electric current
Desincrustation
is process used to soften and emulsify grease deposits (oil) and blackheads in the hair follicles.
violet ray
Tesla high-frequency current It is commonly called
Tesla high- frequency current
is a thermal or heat - producing current with a high rate of oscillation or vibration
steamer or vaporizer
produces moist, uniform heat that can be appiled to the head or face
wavelength
The distance between two successive peaks is called the
Ultraviolet (UV) rays
makes up 5% of natural sunlight
cold rays or actinic rays
ultraviolet (UV) rays are also referred to as
30 to 36 inches
Uv rays are applied with a lamp at a distance of
True
Tesla high frequency current should not be used on clients who pregnant, suffer from epilepsy or asthma, high blood pressure, sinus blockage, pacemaker or metal implants
measures strength of electric current
amp
AC
meaning Alternating Current
Fuse and circuit breaker
prevents current from overload or excessive overload of circuit
ohm
is a unit that measures the resistance of an electric current
watt
is a measurement of how much electric energy is being used in one second
