|
a measure how much electrical energy is being used |
|
|
INSULATOR |
a material that dose not allow the flow of electric current |
|
|
CONDUCTOR |
a material that allows electric to flow through easily |
|
|
ELECTROTHERAPY |
the application of electrical currents during treatment to the skin |
|
|
ELECTRCITY |
a form of energy that produces light, heat,magnetic and chemical changes |
|
|
2 forms of Electric Current |
1.DC or direct current 2.AC or alternating current |
|
|
DC |
direct current in which electrons move at even rate and flow in one direction |
|
|
AC |
alternating current in which electrons flow first in one direction and then in the other |
|
|
2 common sources of electric current |
1. baterry 2.generator |
|
|
OVERLOAD |
more currents flow than the line is designed to carry |
|
|
LOCAL SHOCK |
passes through a small part of the body,causing burn and muscle contractions |
|
|
GENERAL SHOCK |
passes through the nervous system |
|
|
3 types of electrically powered equipment used in the salon |
1.Thermal 2.mechanical 3.combination of thermal and mechanical |
|
|
CIRCUIT BREAKER |
a reusable device that breaks the flow of the current when an overload occurs |
|
|
SHORT CIRCUIT |
occurs anytime a "foreign conductor" comes in contact with a wire carrying current to a load |
