- 28. current, Flow of electricity along a conductor
- 29. current, Abbreviated as DC; constant, even-flowing current that travels in one direction only and is produced by chemical means
- 33. Abbreviated as O; unit that measures the resistance of an electric current
- 35. light, The part of the electromagnetic spectrum that can be seen; visible light makes up only 35 percent of natural sunlight
- 38. current, 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
- 40. Process of infusing water-soluble products into the skin with the use of electric current, such as the use of the positive and negative poles of a galvanic machine
