Elec. Safety
What is the first step you must take after feeling a light electric shock while using an appliance?
What is an ampere?
Unit of measurements for the amount/density of current running through a wire
What is an electrode?
An applicator for directing the electric current from the machine to the clients skin
What is direct current?
current that is constant, even-flowing current traveling in one direction
What is an insulator?
A material that prevents the flow of electricity
(rubber, glass, wood, etc)
What is a fuse and what is it used for?
A device that melts, pops, or explodes when excessive amounts of electricity are flowing through a system to prevent overload
What is a volt?
Unit of measuring the pressure that forces the electric current forward
What is disincrustation?
The process used to soften and emulsify grease deposits and blackheads in the hair follicles
What is Tesla high-frequency current?
a thermal or heat-producing current with a high rate of oscillation or vibration
What is a microcurrent?
an extremely low level of electricity that mirrors the body's natural electrical impulses
What does it mean if an appliance is UL certified?
UL certification means that they are safe when used according to the manufacturer’s direction
What is an Ohm?
Unit of measuring the resistance of an electric current
What is the difference between anaphoresis and cataphoresis?
(-) anaphoresis - the process or forcing liquids into the tissues from negative toward the positive poles. opens pores, stimulates nerves
(+) cataphoresis - forces acidic substances into deeper tissues using galvanic current. closes pores, soothes nerves
What is a rectifier?
device used to change alternating currents into direct currents
What type of current is a galvanic current?
constant & direct form of modality
What is the main purpose of a grounding pin?
It guarantees a safe path for electricity and protects the user from electrical shock.
What is a Watt?
Measurement of how much electric energy is being used in one second
What is anaphoresis?
the process or forcing liquids into the tissues from negative toward the positive poles.
What is a converter?
Device used to change direct current into alternating currents
How much of the light spectrum is visible to the human eye?
about 35%
Why can't you have one hand near an outlet and the other near an appliance that came into contact with water?
You will get shocked because water is a conductor of electricity
What is a milliampere?
One-thousandth of an ampere
What kind of changes do galvanic currents produce?
Chemical
What is the biggest difference between direct current and alternating current?
DC flows in one direction, whereas AC flows back and forth.
Positive to Negative
