category 1
The movement of electrons from one atom to another along a conductor.
electricity
An apparatus that changes direct current to alternating current.
invertor
The current that is used for facial treatments
microcurrent
completes and electric circuit and carries the current safely away.
grounding
this refers to the poles of an electric current, either positive or negative.
polarity
this is material that allows electricity to flow freely through it
conductor
A rapid interrupted current that flows first in one direction than in the opposite direction. It is produced by mechanical means
alternating current
The unit that measures the resistance of an electric current.
OHM
designed to protect from electrical shock by interrupting a household circuit when there is a leak in the circuit.
Ground fault interrupter
a condition that makes it impossible to to a service is a:
contraindication
aka insulator. a material that does not let electricity flow freely through it.
non-conductor
an apparatus that changes alternating current to direct current. phone chargers use this to charge their batteries.
rectifier
The unit measures how much electricity/electric energy is being used.
WATT
all electrical appliances must be certified by:
underwriters laboratories UL
also known as violet ray, this thermal or heat-producing current with a high rate of oscillation or vibration that is commonly used for scalp and facial treatments
tesla high frequency
The path that negative and positive electric currents take from the generating source through the conductors and back to the generating source.
Complete electric circuit
The unit that measures the force or pressure that pushes an electric current forward through a conductor.
VOLT
1000 WATTS
A switch that interrupts or shuts off an electric circuit at the first sign of an overload
circuit breaker
the name was given to all forms of energy (or radiation) that exist
electromagnetic spectrum
a constant even flowing current that travels in one direction only and is produced by chemical means.
direct current
The unit that measures the strength of an electric current.
ampere
Prevents excessive current from passing through a circuit. designed to blow out or melt when wires become overheated.
fuse
the term used for treating the skin or scalp with electricity
electrotherapy
the distance between successive peaks of electromagnetic waves
wave length
