|
Load |
Any electrical appliance |
|
|
Watt |
How much electricity is being used |
|
|
Converter |
Used for DC-run loads; changes the electrons to flow along an alternated current |
|
|
Closed circuit |
Path electrons flow, leaving source to work the appliance (like a blow dryer switched 'on') |
|
|
Parallel wiring |
Powers several loads either simultaneously or at different times |
|
|
Safety devices |
Fuses, circuit breakers, grounding wires |
|
|
Electricity |
A form of energy producing heat, light, magnetic, or chemical changes |
|
|
Conductor |
Material which allows electricity to pass through |
|
|
Conductor materials |
Silver, copper, graphite, carbon, water with ions |
|
|
Insulator |
Material which does not allow electricity to pass through |
|
|
Insulator materials |
Wood, plastic, rubber, alcohol, pure distilled water |
|
|
Amp |
Strength of electricity |
|
|
Hertz |
Frequency of electricity |
|
|
Open circuit |
Path on which electron flow is broken (like a plugged in blow dryer not turned on) |
|
|
Overload |
Too many loads on one circuit being operated at one time, more than the current allows for |
|
|
Fuse |
Safety device containing a fine metal wire allowing current to flow through, and is connected directly to circuits in power box. Metal wire breaks in overload event, rendering it subsequently unusable |
|
|
Local shock |
Electricity passing through small part of one's body |
|
|
General shock |
Electricity passing through nervous system |
|
|
Electrical fire emergency procedure |
1) turn off circuit 2) smother with rug, heavy towel, powder, or fire extinguisher |
|
|
Mechanical equipment |
Clippers Massagers |
