Electricity5

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 Current7

Direct current: (DC) Constant even flowOne 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

Conductors vs. Insulators8

Activity9

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 Electricity10

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 Cost12

AMP x VOLTS = WATTS

WATTS / 1000 = KW (kilowatt)

KW X HOURS USED = KWH

KWH X 0.12(COST) = COST PER MONTH

Activity13

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 Work14

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 Currents29

Modality : refers to the flow of electricity along a conductor

4 main types: Galvanic High Frequency Faradic Sinusoidal

Phoresis30

The process of forcing a water based solution into the skin by using Galvanic current.

Two types Anaphoresis

Cataphoresis

Polarity31

Indicates negative or positiveNanode- 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

33Sparking……

More oxygen isAllowed into the area creating a spark gap

Two methods of High Frequency

34

Direct HF35

Activity36

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 Current37

alternating current that produces a mechanical reaction w/out a chemical effect

Sinusoidal Current38

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 Measures39

Light Therapy42

Treatment by means of light. These rays travel at 186,000 miles per second.

Short waves= XraysLonger waves= TV or Radio

Visible Light: light we can see.43

Invisible Light44

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
