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 4 Electricity 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 1 st 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 / 1000 = KW (kilowatt) KW X HOURS USED = 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?

Electric Currents 29 Modality : refers to the flow of electricity along a conductor 4 main types: Galvanic High Frequency Faradic Sinusoidal

Phoresis 30 The process of forcing a water based solution into the skin by using Galvanic current. 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. Galvanic High Frequency Faradic Sinusoidal Create one slide per topic Show at lease one illustration List the important information found on page 185 -186

Light Therapy 42 Treatment by means of light. These rays travel at 186, 000 miles per second. Short waves= Xrays Longer waves= TV or Radio

Visible Light: light we can see. 43

Invisible Light 44 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

Infrared Light or IR light 45 Produces Heat Benefits: Increases circulation Relaxes muscles Stimulates cell activity

Ultraviolet Light 46 UVC UVB UVA
