Question The movement of electrons from one atom to another along a conductor is called____. Electric wires can be covered with a material that does not transmit electricity such as a rubber or plastic coating. This material is known as_____. An apparatus that changes direct current to alternating current is_____. The term_____ refers to a rapid and interrupted current, flowing first in one direction and then in the opposite. The unit that measures that pressure or force that pushes the electric current forward through a conductor is_____. Which unit measures the resistance of an electric current? The device that prevents excessive current from passing through a circuit is called_____. A switch that automatically interrupts or shuts off an electric current at the first indication of an overload is_____. The negative electrode of an of an electrotherapy device is called_____. A process that infuses an alkaline product into tissues from the negative pole toward the positive pole called_____. Grounding completes __________ and carries the current safely away. All the electrical appliances you use should _______. When using _______, the active electrode is the electrode used on the area to be treated. Microcurrent can be used to ______ and restore elasticity. Only licensed professionals should use ________. A wavelength is the distance between successive peaks of ____ waves. Invisible light is the light at either end of the ______ that is invisible to the naked eye. Ultraviolet C (UVC) light________. Catalysts are substances that speed up _______. All lasers work by a process known as selective ________. Consistent and direct current, having a positive and negative pole, which produces chemical changes when it passes through the tissues and fluids of the body is known as _______ current. An extremely low level of electricity that mirrors the body's natural electrical impulses is _______. A medical device that uses multiple colors and wavelengths of focused light to conditions such as excessive hair and spider veins is _______. The thermal or heat-producing current with a high rate of oscillation or vibration that is commonly used for scalp and facial treatments is called _______. A device that works by releasing light onto the skin to stimulate specific responses at precise depths of the skin tissue is ______. For safety, use no more than ______ plug(s) in each outlet. When ____ is heated, it produces positive and negative ions that cancel the electric charges in the hair that cause static electricity.
