basics of electricity
The flow of electrons through a conductor
What is an electric current
The type of current that flows in one direction only
What is a direct current
This electrical modality produces heat and is commonly used in high frequency machines
What is Tesla high frequency current
This type of light is Used in LED therapy to help hill acne causing bacteria
What is blue light
This device protects against electrical shock in the treatment room
What is a GFCI/GFI
The unit used to measure the strength of an electric current
What is an ampere/amp
The type of current that periodically reverses direction
What is an alternating current
This current produces chemical changes and is used in desincrustation
What is galvanic current
This LED light is commonly used for anti-aging and stimulating collagen
What is red light
This occurs when electricity passes through the body
What is an electric shock
The pressure that pushes electric current through a conductor
What is voltage
This type of current is commonly used in esthetic machines
What is alternating current
A low-level current that mimics the body’s natural electrical current
What is microcurrent
These are invisible rays that penetrate deeper than visible light
What are infrared rays
Equipment must be checked regularly to ensure this safety feature is intact
What is proper grounding
A complete path that electricity travels through
What is a circuit
This current is used in devices like batteries
What is direct current
This treatment uses galvanic current to soften sebum and debris in the pores
What is desincrustation
The portion of the electromagnetic spectrum (EMS) visible to the human eye
What is visible light
Estheticians should avoid using electrical equipment with this condition
What is frayed or damaged cords
A material that allows electricity to flow through it easily
What is a conductor
The rate at which alternating current changes direction per second
What is frequency
This treatment uses galvanic current to push water-soluble products into the skin
What is iontophoresis
This type of light can stimulate circulation and improve skin health in treatments
What are LED light treatments
This step should always be done before cleaning electrical equipment
What is unplugging the device
