A form of energy that, when in motion exhibits magnetic, chemical, or thermal effects.
What is electricity?
100
A constant, even-flowing current that travels in one direction only.
What is direct current (DC)?
100
The unit that measures the pressure or force that pushes the flow of electrons forward through a conductor, much like the water pressure that pushes the water molecules through a hose.
What is a volt (V)?
100
A special device that prevents excessive current from passing through a circuit. It is designed to blow out or melt when the wire becomes too hot from overloading the circuit with too much current.
What is a fuse?
100
An instrument that plugs into an ordinary wall outlet and produces different types of electric currents that are used for facial and scalp treatments.
What is a wall plate?
200
The flow of electricity along a conductor.
What is electric current?
200
A rapid and interupted current, flowing first in one direction and then in the opposite.
What is alternating current (AC)?
200
The unit that measures the amount of electric current (the number of electrons flowing through a conductor).
What is an amp(A) or ampere?
200
A switch that automatically interrupts or shuts off an electric circuit at the first indication of overload.
What is a circuit breaker?
200
Electric currents that are used for facial and scalp treatments.
What are modalities?
300
The path of an electric current from the generating source through conductors and back to its orginial source.
What is a complete circuit?
300
An apparatus that changes direct current to alternating current.
What is a converter?
300
One-thousandth of an ampere.
What is a milliampere?
300
An apparatus that changes alternating current to direct current.
What is a rectifier?
300
An applicator for directing the electric current from the machine to the client's skin.
What is an electrode?
400
Any substance that easily transmits electricity. i.e. most metals, especially copper, water.
What is a conductor?
400
An apparatus that changes alternating current to direct current.
What is a rectifier?
400
A unit that measures the resistance of an electric current.
What is an ohm (O)?
400
An apparatus that changes direct current to alternating current.
What is a converter?
400
This indicates negative or positive pole of an electric current.
What is polarity?
500
A substance that does not easily transmit electricity. i.e. rubber, silk, wood, glass and cement.
What is an insulator or nonconductor?
500
A measurement of how much electric energy is being used in 1 second.
What is a watt (W)?
500
A substance that does not easily transmit electricity. i.e. rubber, silk, wood, glass, and cement.
What is an insulator?
500
A positive electrode usually marked with a "P" or a (+) sign.
