  1. Mon. 9/17/12 Salon Fundamentals Book Read Chapter 6 Starting on page 175 to 178

  2. Basics Of Electricity

  3. Journal Question • Industrialized societies are very dependent upon electrical power. How would the services provided by a skin care center be diminished if electricity suddenly become unavailable? • What would you offer a client instead?

  4. Key TermsDefine each of these words on note cards • Electricity • Electric Current • Conductor • Load • Insulator • Amp • Volt • Ohm • Watt • Electrotherapy QUIZ NEXT CLASS

  5. Electricity Electricity: is the form of energy that produces light, heat, magnetic & chemical changes. Electric current: the flow of electricity along a conductor

  6. Do the Walk About……

  7. Types of Electric Current • Direct current: (DC) • Constant even flow • One direction only • (ex. flashlights, cell phones) • Converter is a device that changes DC to AC • Alternating current: (AC) • Rapid & interrupted • Flowing 1st in one direction and then in the opposite • (ex hair dryers & curling irons) • Rectifier is a device that changes AC to DC

  8. Conductors vs. Insulators

  9. Activity • Each group will research one of the following and place information on the paper provided. You may use your book or internet to do this. • Amp • Volt • Ohm • Watt • Then the group will report back to the class your findings

  10. Measurements of Electricity • Amp: strength of the current. • The higher amp rating indicates a greater number of electrons and a stronger current. • Volt: pressure • pushes the flow of electrons forward through a conductor • Milliamper: one-thousandth of an amper. • Used to measure the current for facial treatments.

  11. ohm: resistance of an electric current. • Current will not flow through the conductor unless the force (volts) is stronger than the resistance (ohm). • Watt: a measurement how much energy is being used in one second. • (ex. a 40 watt light bulb uses 40 watts of energy per second. • Kilowatt: is 1,000 watts.

  12. Calculate Cost AMP x VOLTS = WATTS WATTS / 1000 = KW (kilowatt) KW X HOURS USED = KWH KWH X 0.12(COST) = COST PER MONTH

  13. Activity How much does that cost? • Amy uses her flat iron 30 minutes each day for 30 days. It uses 120 amps and 60 volts of electricity. The electric company charges $0.08 per KWh • How many watts does Amy flat iron use? 2. How much does it cost for Amy to use her flat iron each month?

  14. Home Work Choose an appliance from home and use the formula provided to find out how much it cost per month to use the piece of equipment. Submit it via- the website

  15. How much does that cost? • Brianna uses her flat iron 20 minutes each day for 30 days. It uses 120 amps and 60 volts of electricity. The electric company charges $0.08 per KWh • How many watts does Brianna’s flat iron use? • How much does it cost for Brianna to use her flat iron each month?

  16. Wed. September 19,12 • Go to X drive read Electrical Safety in the salon & Blog • Vocab. Quiz • Home Work • Read page 179-184 • Discussion • Safety Activity

  17. Electrical Safety • Circuit= closed path • Open circuit= when this path is broken

  18. OVERLOAD

  19. Electrical Fire Safety OVERLOAD

  20. Safety Devices • Fuse • Circuit breaker • These have replaced fuses in modern circuits

  21. Shock Local General

  22. Fire Safety

  23. Fire Triangle Heat Oxygen ChemicalReaction Fuel

  24. Fire extinguisher operation • P = PULL PIN • A = AIM NOZZLE • S = SQUEEZE HANDLE • S = SWEEP AT BASE OF FIRE

  25. Activity

  26. Out the door • Go to m.socrative.com • Room 92576

  27. Wed. 9/26/12 • Read page 185-190 & fill out smart notes for this section • Discussion • Power Point Activity • Key Terms on page 188 using quizlet.com

  28. Electric Currents • Modality : refers to the flow of electricity along a conductor • 4 main types: • Galvanic • High Frequency • Faradic • Sinusoidal

  29. Phoresis • The process of forcing a water based solution into the skin by using Galvanic current. • Two types • Anaphoresis • Cataphoresis

  30. Polarity • Indicates negative or positive • Nanode- positive current, usually red and marked w/a P or (+) • Cathode- negative electrode, usually black and marked w/a N or (-) • Do not let the tips of the cords touch or you will cause a short circuit.

  31. High Frequency Current Tesla Current and produces heat Filled with: Argon gas (used for acne lesions) Neon gas (normal to oily to improve product penetration or increase circulation) • Ozone

  32. Sparking…… More oxygen is Allowed into the area creating a spark gap

  33. Two methods of High Frequency

  34. Direct HF

  35. Activity • You will break into 4 groups • Read about Faradic Current or Sinusoidal Current • Your group will then write on the paper provided the benefits

  36. Faradic Current alternating current that produces a mechanical reaction w/out a chemical effect

  37. Sinusoidal Current alternating current that produces mechanical contractions that tone the muscles. Benefits include Greater stimulation, deeper penetration, and less irritating Soothes the nerves and penetrates into deeper muscle tissue Is best suited from the nervous client

  38. Precautionary Measures

  39. Activity • Create a power point of the 4 main types of electrotherapy currents. • Galvanic • High Frequency • Faradic • Sinusoidal • Create one slide per topic • Show at lease one illustration • List the important information found on page 185-186

  40. Tuesday September 20,11 • Read pages 194-213 & log • Discuss Light Therapy • Break • Study Guide for Test Thursday

  41. Light Therapy • Treatment by means of light. These rays travel at 186,000 miles per second. • Short waves= Xrays • Longer waves= TV or Radio

  42. Visible Light: light we can see.

  43. Invisible Light Infrared Rays 60% of all natural light long wave lengths penetrate all skin layers produce the most heat Ultraviolet Rays short wavelengths least penetrating Produce chemical effects & kill germs

  44. Infrared Light or IR light Produces Heat Benefits: • Increases circulation • Relaxes muscles • Stimulates cell activity

  45. Ultraviolet Light • UVC • UVB • UVA

  46. Monday October 8, 12 • Do Practice Test • Review Light therapy • Go over study guide…test next class

  47. Journal Prompt • In your own words describe the effects of thermal mechanical and electrochemical currents upon the human skin.

  48. Wed. October 10 Journal: Describe the benefits of using direct high frequency on a client.

  49. Wed. October 10 • Journal • Discuss light therapy • Review • Practice Test
