Basics of Electricity in Cosmetology

Basics of Electricty Question Electricity does not occupy space or have physical or chemical properties. Distilled water is a particularly good conductor. There are two types of electric current: direct and converted. Normal electric wall sockets that power a hair dryer or curling iron are 220 volts. The heating element in a hair dryer heats up because it is not large enough to carry the electric current. A wall plate is also known as facial stimulator. Microcurrent travels throughout the entire body. UV prompts the skin to produce vitamin D, a fat-soluble vitamin that promotes mineralization of bones. Ultraviolet A light has the longest wavelength of the UV light spectrum. Electricity is a form of energy that, when in motion, exhibits: a. thermal effects c. chemical effects b. magnetic effects d. all answers correct Lightning bolts travel through the air at speeds of up to how many miles per hour? A substance that is a particularly good conductor of electricity is: The path of an electric current from the generating source back to the original source is a(n): Rubber, silk, wood, and glass are common examples of: Rapid and interrupted current that flows in one direction and then in the opposite direction is: Electricity travels how many miles per second? The unit that measures the pressure or force that pushes the flow of electrons forward through a conductor is a(n): The current for facial and scalp treatments is measured in: A measurement of how much electricity is being used in 1 second is a(n): The special device that prevents excessive current from passing through a circuit is a(n): The electrical appliance connection that supplies current to the circuit is the: Electronic facial treatments are commonly referred to as: An applicator that directs electric current from a machine to the client’s skin is a(n): The negative or positive pole of an electric current is referred to as the: The positive electrode is called a(n): Infusing water-soluble products into the skin with the use of electric current is known as: Cataphoresis forces acidic substances into deeper tissues using galvanic current from the: The process used to treat acne and milia and soften and emulsify deposits in the hair follicles is: Thermal or heat-producing current with a high rate of oscillation or vibration is: The type of current that should not be used on clients who are pregnant, have high blood pressure, or have a pacemaker is: The distance between two successive peaks is called: Rays with short wavelengths that are the least penetrating, produce chemical effects, and kill germs are: Rays with long wavelengths that penetrate more deeply and produce more heat than visible light are: Lasers work by a process that turns the light from the laser into heat called: Substances that speed up chemical reactions Unit that measures the strength of an electric current Unit that measures the resistance of an electric current Currents used in electrical facial and scalp Answer True False False False True True False True True d. all answers correct 60.000 Copper complete circuit insulators alternating current 186,000 Volt milliamperes watt Fuse live connection electrotherapy electrode polarity anode iontophoresis positive toward the negative pole desincrustation violet ray Tesla high-frequency wavelength ultraviolet rays infrared rays photothermolysis Catalysts Ampere Ohm Modalities Extremely low level of electricity that mirrors the body’s natural electrical impulses Color component within the skin such as blood or melanin Microcurrent Chromophore
