Mon. 9/17/12 1 Salon Fundamentals Book Read Chapter 6 Starting on page 175 to 178 2 Basics Of Electricity Journal Question 3 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? Key Terms Define each of these words on note cards Electricity 4 Amp Electric Current Volt Conductor Ohm Load Watt Insulator Electrotherapy QUIZ NEXT CLASS Electricity 5 Electricity: is the form of energy that produces light, heat, magnetic & chemical changes. Electric current: the flow of electricity along a conductor Do the Walk About…… 6 Types of Electric Current 7 Direct current: (DC) Constant even flow One direction only (ex. flashlights, cell phones) Alternating current: (AC) Rapid & interrupted Flowing 1st in one direction and then in the opposite (ex hair dryers & curling irons) Converter is a device that changes DC to AC Rectifier is a device that changes AC to DC Conductors vs. Insulators 8 Activity 9 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 Measurements of Electricity 10 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. Calculate Cost 12 AMP x VOLTS = WATTS WATTS / 1000 = KW (kilowatt) KW X HOURS USED = KWH KWH X 0.12(COST) = COST PER MONTH Activity 13 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 1. How many watts does Amy flat iron use? 2. How much does it cost for Amy to use her flat iron each month? Home Work 14 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 How much does that cost? 15 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? Wed.

Two types Anaphoresis Cataphoresis Polarity 31 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. High Frequency Current 32 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 Sparking…… 33 More oxygen is Allowed into the area creating a spark gap Two methods of High Frequency 34 Direct HF 35 Activity 36 You will break into 4 groups Read about Faradic Current or Sinusoidal Current Your group will then write on the paper provided the benefits Faradic Current 37 alternating current that produces a mechanical reaction w/out a chemical effect Sinusoidal 38 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 Precautionary Measures 39 Activity 40 Create a power point of the 4 main types of electrotherapy currents.
