Chapter 6: Electricity Flashcards
electric current in which electrons move at an even rate and flow only in one direction
Direct Current
electric current in which electrons flow first in one direction and then in the other
Alternating current
electrocution passing through the nervous system
General shock
electricity passing through a small part of the body
Local shock
a circuit through which electricity can travel
Closed path
a broken path through which electricity can not travel
Open circuit
occurs anytime a conductor comes into contact with a wire carrying current to a load (appliance)
Short circuit
two metal pieces that make contact with each other to allow the flow of electric current are found on this
Circuit breaker
the technical term for any electrically powered appliance
Load
when more current flows through a line than it is designed to carry
Overload
breaks the flow of current when an overload occurs
Circuit breaker
three-wire system that is designed to protect the user during the operation of appliances, especially metal ones
Grounding wire
indicates the amount of current flowing through equipment and regulates the amount via a dial or knob
Rheostat
a safety device that prevents electrical wires from overheating
Fuse
positive end of an electrode
Anode
negative end of an electrode
Cathode
a material that allows electricity to flow through it easily
Conductor
a material that does not allow the flow of electric current
Insulator
high frequency method that creates an even more powerful ozone effect by slowly lifting the electrode away from the skin
Sparking
type of phoresis that allows an acidic solution to enter the skin which assisted by Galvanic Current and the positive pole of an electrode
Cataphoresis
type of phoresis that allows an alkaline solution to enter the skin when assisted by Galvanic Current and the negative pole of an electrode
Anaphoresis
term used to describe the electrode held by the client
Inactive electrode
term used to describe the electrode held by the esthetician
Active electrode
having opposite poles in electrical current
Polarity
light that can produce cool or blue tones
Fluorescent lights
light that can produce warm or red tones
Incandescent lights
combination light that can be broken into its individual wavelengths by a prism
White light
indicates the number of cycles per second that a generator alternates current
Hertz Rating
a unit of electric resistance
Ohm
a unit of electric pressure
Volt
a unit of electric strength
Amp
a measure of electrical energy being used
Watt
alternating current that is interrupted to produce a mechanical, non-chemical reaction
Faradic current
resistance to the motions of electrons through a conductor
Ohms Rating
Power companies describe watt usage in What?
Kilo watt hours
method where esthetician places both electrodes on the client’s skin, being certain the electrodes never touch
Direct faradic
most frequently used method of Faradic current in which the esthetician usually wears a wristband with a moistened electrode
Indirect faradic
alternating current that produces a mechanical effect but that can penetrate deeply and provide greater stimulation
Sinusoidal current
