electricity
what is the movement of electrons from one atom to another along a conductor.
direct current
what is a constant, even-flowing current that travels in one direction only and is produced by chemical means
ampere
what is the unit that measures the strength of an electric current
fuse
what prevents excessive current from passing through a circuit
modalities
currents used in electrical facial and scalp treatments
electric current
what is the flow of electricity along a conductor.
inverter
what is an apparatus that changes direct current to alternating current
milliampere
what is 1/1000 of an ampere
circuit breaker
what is switch that automatically interrupts or shuts off an electric circuit at the first indication of an overload
electrode
what is also known as a probe, and applicator for directing electric current from an electrotherapy device to the client's skin
conductor
what is any material that conducts electricity
alternating current
what is a rapid and interrupted current, flowing first in one direction and then in the opposite direction, it is produced by mechanical means and changes directions 60 times per second
ohm
what is a unit that measures the resistance of an electric current
grounding
what completes an electric circuit and carries the current safely away
polarity
what refers to the poles of an electric current, either positive or negative
nonconductor
what is also known as an insulator, is a material that does not transmit electricity.
rectifier
what is an apparatus that changes alternating current to direct current
watt
what is a unit that measures how much electric energy is being used in one second
ground fault interurupter
what is designed to protect from electrical shock by interrupting a household circuit when there is a leak in the circuit
anode
what is the positive electrode
complete electric circuit
what is the path that negative and positive electric currents take from the generating source through conductors and back to the generating source
volt
what is the unit that measures the pressure or force that oushes electric current forward through a conductor
kilowatt
what is 1,000 watts
electrotherapy
what is the use of electrical currents to treat the skin
cathode
what is the negative electrode
