| Question | Answer |
| The flow of electricity along a conductor. | Electric current |
| Any substance that easily transmits electricity.most metals are good conductors. | Conductor |
| A substance that does not easily transmit electricity.rubber,silk,wood,glass,and cement are good insulators. | Insulator or nonconductor |
| A constant,even flowing current that travels in one direction only. | Direct current DC |
| An apparatus that changes direct current to alternating current. | Converter |
| A rapid and interrupted current,flowing first in one direction and then in the opposite direction. | Alternating current AC |
| An apparatus that changes alternating current to direct current. | Rectifier |
| The unit that measures the pressure or force that pushes the flow of electrons forward through a conductor. | Volt V |
| The unit that measures the amount of an. Electric current | Amp |
| One thousandth of an ampere. | Milliampere |
| A unit that measures the resistance of an electric current | Ohm |
| A measurement of how much electric energy is being used in 1 second | A watt |
| Is 1,000 watts.the electricity in your home is measured in this | Kilowatt |
| A special device that prevents excessive current from passing through a circuit. | Fuse |
| A switch that automatically interrupts or shuts off an electric circuit at the first indication of overload | Circuit breaker |
| An insrument that plugs into an ordinary wall outlet and produces different types of electric current that are used for facial and scalp treatments. | Wall plate |
| An applicator for directing the electric current from the machine to the clients skin. | Electrode |
| Indicates the negative or positive pole of an electric current | Polarity |
| The positive electrode from a electrotherapy devices. | Anode |
| The negative electrode from a electrotherapy devices | Cathode |
| Two main modalities used in cosmetology | Galvanic and Tesla |
| The most commonly used modality.It is a constant and direct current DC having a positive and negative pole and produces chemical changes when it passes through the tissues and fluids of the body. | Galvanic current |
| The process of introducing water soluble products into the skin with the use of electric current,such as the use of the positive and negative poles of a galvanic machine. | Iontophoresis |
| Forces acidic substances into deep tissues using galvanic current from the positive toward the negative pole. | Cataphoresis |
| The process of forcing liquids into the tissues from the negative toward the positive pole. | Anaphoresis |
| A process used to soften and emulsify grease deposits and blackheads in the hair follicles. | Desincrustation |
| A thermal or heat producing current with a high rate of oscillation or vibration. | Tesla high frequency current or violet rays |
| Another name for radiant energy because it carries,or radiates,energy through space on waves | Electromagnetic radiation |
| The distance between two successive peaks | Wavelength |
| Made up of 60 percent of natural sunlight ,have longer wavelength,penetrate deeper,and produce more heat than visible light. | Infrared |
| Primary source of light used in facial and scalp treatments.35 percent natural light | Visible light |
| Referred to as combination light because it is a combination of all visible rays of the spectrum. | White light |
| Make up 5 percent of natural sunlight,and are also referred to as cold rays or actinic rays. | Ultraviolet rays |
| Used to make reactions happen more quickly. | Catalyst |
| Light cured nail enhancements use | UV light |
