Across
- 2. Has a positive terminal (+) and a negative (-) terminal and produces direct current ONLY.
- 4. One one-thousandth (1/1000) of an ampere; a unit of measurement used to describe the intensity of an electrical current. Used for microcurrent in the salon.
- 9. A unit of electric resistance.
- 12. When too many appliances are put on one circuit and are operated at the same time. More current flows than the line is designed to carry.
- 13. A path of electron flow from the source to operate an appliance. When a circuit is close, the appliance is on.
- 15. A form of energy that produces light, heat and magnetic and chemical changes.
- 16. A reusable safety device that breaks the flow of current when an overload occurs. It contains two pieces of metal that make contact with each other.
- 18. A safety device that contains a fine metal wire that allows current to flow through it. If an overload occurs the fuse will heat up and the wire will melt breaking the circuit and cutting the flow of electricity.
- 19. Can occur anytime a foreign conductor comes in contact its a wire carrying current to a load (appliance). This commonly occurs in thermal styling tool cords. Twisting, and bending cords will eventually break the copper wires and if you touch the break you'll get an electric shock.
- 20. Also known as DC. It is the direction in which electrons move at an even rate and flow in only one direction.
- 21. When the path of the electrons is broken. When an appliance is off it is considered an open circuit.
Down
- 1. The movement of electricity along a path called a conductor. It exists in two different forms, AC or DC.
- 3. A unit of electric strength.
- 5. Also known as AC. The direction in which electrons flow first in one direction nd then in the other. (wall socket)
- 6. 1,000 watts =1 Kilowatt.
- 7. Material that allows electricity to follow through it easily. Best ones are copper and silver. Other metals, graphite, carbon and water-containing ions allow current to flow as well. Since the human body is 60% water it can also be considered a conductor.
- 8. A unit of electric pressure. AC generators force or push 120 or 240 volts in a circuit.
- 10. Ground fault circuit interrupter. Recommended for installation in any area where water and electricity could come into contact with each other.
- 11. Underwriter's Laboratory designation; means the electrical appliance has been certified to operate safely under the conditions the instructions specify.
- 14. A measure of how much electrical energy (power) is being used per second.
- 17. Material that does not allow a current to pass through it. They protect you from electric current and allow you to handle electricity safely. Examples include silk, plastic, rubber, wood, glass, paper, air, brick, cloth and certain liquids like alcohol and pure distilled water.
