Electricity Flashcards
Apparatus that changes alternating current to direct current, mobile phone charges convert ac current to dc current needed to recharge batteries
Rectifier
Unit that measures the pressure or force that pushes the flow of electrons forward through a conductor
Volt
Unit that measures the amount of an electric current ( number of electrons flowing through a conductor)
Ampere
One-thousandth of an ampere
Milliampere
Unit that measures the resistance of an electric current
Ohm
Measurement of how much electric energy is being used in 1 second
Watt
1,000 watts
Kilowatt
Prevents excessive current from passing through a circuit
Fuse
Switch that automatically interrupts or shuts off an electric circuit at the first indication of an overload
Circuit breaker
Ground connection completes the circuit and carries the current safely away to the ground
Grounding
Use of electrical devices to treat the skin and for therapeutic benefits
Electrotherapy
Currents used in electrical facial and scalp treatments
Modalities
Applicator for directing the electric current from the device to the clients skin
Electrode or probe
One negative one positive– to conduct the flow of electricity through the body
2 electrodes, each modality requires 2 except for tesla high frequency
Indicates the negative or positive pole of an electric current
Polarity
Positive electrode
Anode, usually red and I’d marked with a P or plus sign
Negative electrode black and is usually marked with an N or a minus sign
Cathode
Constant and direct current. It has a positive and negative pole and produces chemical changes when it passes through the tissues and fluids of the body
Galvanic current
Electrode used on the area to be treated
Active electrode
Opposite pole from the active electrode
Inactive electrode
Process of introducing water-soluble products into the skin with the use of electric current
Iontophoresis also known as ionization
Infusing a positive (acid) product into the skin with the use of electric current
Cataphoresis
Process of infusing a negative (alkaline) product into the skin
Anaphoresis
Form of anaphoresis and is a process used to soften and emulsify grease deposits and blackheads in the hair follicles
Desincrustation
Extremely low level of electricity that mirrors the bodys own natural electrical impulses
Microcurrent
Thermal
or heat producing current with a high rate of oscillation or vibration
Tesla high frequency current. Also known as violet ray
Electromagnetic radiation that we can see. Primary source of light used in facial and scalp treatments
Visible light
Distance between two successive peaks
Wavelength
Naked eye cannot perceive, light at either end of the visible spectrum of light that is invisible to the naked eye
Invisible light
Shorter wavelengths, penetrate less, and produces less heat than visible heat does, produce chemical effects, and kills germs
Ultraviolet radiation. UV
Beyond the visible red light of the spectrum, produces heat, longer wavelengths , penetrates more deeply, has less energy, and produces more heat than visible light, makes up 60% of natural sunlight
Infrared light
Longest wavelength , penetrates directly into the dermis of the skin and damages collagen and elastin
Ultraviolet A. UVA
Burning rays
Ultraviolet B UVB
Blocked by the ozone layer
Ultraviolet C UVC
Application of light rays to the skin for the treatment of acne, wrinkles, capillaries, pigmentation, or hair removal
Light therapy. Phototherapy
L.A.S.E.R.
Light amplification stimulation emission of radiation
Process that turns the light from the laser into heat
Photothermolysis
works by releasing light onto the skin to stimulate specific responses, at precise depths of the skin
Light emitting diode
Increases circulation and improves the collagen and elastin production in the skin
Red light
Shown to reduce swelling and inflammation
Yellow light
Reduces hyperpigmentation
Green light
Medical device that uses multiple colors and wavelengths of focused light to treat spider veins, hyperpigmentation, rosacea/redness, wrinkles, enlarged hair follicles/pores, and excessive hair
Intense pulse light
Made up of all forms of energy whose spectrum ranges from the longest waves to the shortest
Electromagnetic spectrum
2 or 3 prong connector at the end of an electrical cord that connects an apparatus to an electrical outlet
Plug
Referred to as combination light because it is a combination of all the visible rays of the spectrum
White light
Electricity is not?
Matter
Provides moist, uniform heat for a facial
Steamer, vaporizer
