  1. 2. completes an electrical circuit and carries the current safely away.
  2. 3. unit that measures how much electric energy is being used in one second.
  3. 6. constant and direct current, having a positive and negative pole, that produces chemical changes when it passes through the tissues and fluids of the body.
  4. 8. unit that measures the pressure or force that pushes electric current forward through a conductor.
  5. 9. unit that measures the strength of an electric current
  6. 10. any material that conducts electricity
  7. 13. unit that measures the resistance of an electrical current
  8. 16. rapid and interrupting current, flowing first in one direction and then in the opposite direction; produced by mechanical means and changes directions 60 times per second.
  9. 17. also know as probe; applicator for directing electric current from an electrotherapy device into the client’s skin.
  10. 18. invisible light with longer wavelengths, deeper penetration, less energy, and more heat production than visible light; makes up 60% of natural sunlight.
  11. 19. Constant, even flowing Current that travels in one direction only and is produced by chemical means.
  12. 20. process of infusing water-soluble products into the skin with the use of electric, such as the use of positive and negative poles of a galvanic machine.

  1. 1. currents used in electrical facial and scalp treatments
  2. 4. substance that speeds up chemical reactions
  3. 5. positive electrode of an electrotherapy device; usually red and marked with a P or (+) sign.
  4. 7. negative electrode of an electrotherapy device; usually black and marked with an N or (-) sign.
  5. 11. also known as insulator; a material that does not transmit electricity
  6. 12. invisible light that has a short wavelength, is less penetrating than visible light, causes chemical reactions to happen more quickly than visible light, produces less heat than visible light, and kills germs.
  7. 14. an extremely low level of electricity that mirrors the body’s natural electrical impulses
  8. 15. switch that automatically interrupts or shuts off an electric circuit at the first indication of overload.
