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?

Electricity5
Electricity: is the form of energy that
produces light, heat, magnetic & chemical
changes.
Electric current: the flow of electricity along a conductor
![Page 6: Mon. 9/17/12](https://reader035.vdocuments.net/reader035/viewer/2022062309/56813c78550346895da60f8e/html5/thumbnails/6.jpg)

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
![Page 8: Mon. 9/17/12](https://reader035.vdocuments.net/reader035/viewer/2022062309/56813c78550346895da60f8e/html5/thumbnails/8.jpg)
Conductors vs. Insulators8
![Page 9: Mon. 9/17/12](https://reader035.vdocuments.net/reader035/viewer/2022062309/56813c78550346895da60f8e/html5/thumbnails/9.jpg)
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
![Page 10: Mon. 9/17/12](https://reader035.vdocuments.net/reader035/viewer/2022062309/56813c78550346895da60f8e/html5/thumbnails/10.jpg)
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.
![Page 11: Mon. 9/17/12](https://reader035.vdocuments.net/reader035/viewer/2022062309/56813c78550346895da60f8e/html5/thumbnails/11.jpg)
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.
![Page 12: Mon. 9/17/12](https://reader035.vdocuments.net/reader035/viewer/2022062309/56813c78550346895da60f8e/html5/thumbnails/12.jpg)
Calculate Cost12
AMP x VOLTS = WATTS
WATTS / 1000 = KW (kilowatt)
KW X HOURS USED = KWH
KWH X 0.12(COST) = COST PER MONTH
![Page 13: Mon. 9/17/12](https://reader035.vdocuments.net/reader035/viewer/2022062309/56813c78550346895da60f8e/html5/thumbnails/13.jpg)
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?
![Page 14: Mon. 9/17/12](https://reader035.vdocuments.net/reader035/viewer/2022062309/56813c78550346895da60f8e/html5/thumbnails/14.jpg)

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?
