102.9-102.10 Electricity Test Question A current in which electrons move at an even rate and flow in only one direction is called: Bacteria that cause skin infections can be killed by: Depending on it's design, which type of light can create blue or cool tones? High frequency current is an alternating current that can be adjusted to different voltages to produce heat? How does a cold setting work on a blow dryer? If the client is holding the active electrode while the salon pro manually stimulates the area being treated, what method of high frequency current is being used? Incandescent light normally produces what color tones in the objects it lights? The chemical breakdown of the skin caused by intense heat? The direct current used in electrotherapy treatments is: The max amount of current used in a galvanic treatment should generally not exceed: The minimum distance an infrared lamp must be placed from the client's face during a facial? The process of forcing an acid or alkali into the skinby applying current to the chemical? What is the timing guideline when using galvanic current for a sensitive skin treatment? When testing electrodes for polarity, the negative electrode will create When the salon pro applies the electrode directly to the clients scalp or face when using high frequency current? A measure of how much electrical energy is being used? A unit of electric resistance is called? A volt is a unit of electric: An amp is a unit of electric: Cords on appliances should be kept straight and free of knots, kinks, and tangles to prevent: Dropping an electrical appliance into water, making it a foreign conductor, causes: Electric current moves along a path called: Glass, rubber, or paper are examples of what type of material? Light, heat, chemical and magnetic changes are produced by: Materials that best transport electricity along a path called a conductor is an: The 2 forms of electric current are: To avoid the possibility of overloads and short circuits, safety devices are installed in appliances and buildings. two of these devices are fuses and: Two common sources of electric current are generators and: When a blow dryer is on and air begins to flow, you have an example of: The movement of electricity along a path called a conductor is a: Answer direct current ultraviolet light flourescent tesla stops all flow of current to the heating element, but still allows current to flow to the dryer indirect application redder tones pyrolysis galvanic 2 milliamperes 30" phoresis 3-5 minutes smaller bubbles direct application watt ohm pressure strength breaks short circuit conductor insulating materials electricity electric current AC / DC circuit breakers batteries closed circuit electric current
