Practice Test 1 Flashcards
The person who signs and seals plans for electrical engineering for the purpose of obtaining a building permit
Professional electrical engineer
Branch of physics pertaining to the phenomena and law of sound including the study of regulating sound and its reflecting properties
Acoustics
An equipment for transporting people or things vertically through the building
Elevator
A process of treating air so as to control simultaneously it’s temperature, humidity, cleanliness, and distribution within interior space such as a room or building
Air conditioning
A pipe sheet metal or conduit fitting having a bend usualy 90 degrees
Elbow
A duct used to transfer air from one location to another
Air duct
A water outlet valve, also called a cock
Faucet
A unit of luminous intensity
Lumen
A nipple having no shoulder and having the shortest possible length permitted by standard practice
1” nipple
*but there are now 1/2” galvanised nipples (ie. Anvil nipple brand)
Color-coding of plastic pipes and fittings for electrical conduit
Orange
In a plumbing system, a branch in the shape of letter y
Wye branch
A power-driven inclined continuous stairway used for raising or lowering passengers
Escalator
What does the letter U in UPVC mean
Un plasticized
A low basin-like fixture on which the user sits, used to wash the posterior parts of the body
Bidet
A unit of flow of electric current
Ampere
A valve for controlling the flow of a liquid or air at right angles to the direction in which it enters the valve
Gate valve
An artificial reservoir or tank for storing water at atmospheric pressure such as rainwater collected from a roof for use when required
Cistern
An over-current protective device consisting of a metal strip, ribbon or wire designed to open an electric circuit by melting if a predetermined current is exceeded
Fuse
A structure, usually on the roof of the building, over which water is circulated so as to cool it evaporately by contact with air
Cooling tower
A short internally threaded section pipe, used to join two pipes or conduits
Flange; connector; nipple; coupling*
A lamp from which light is emitted when tungsten filament is heated to incandescence by an electric current
Incandescent lamp* or fluorescent; tungsten; halogen
A device that redirects light or sound by reflection
Reflector* filter; filament; dimmer
Eisha Graves Otis is known for
Elevators
What is the maximum angle of inclination of an escalator
30 degrees
The flow of water or other liquids in a direction opposite to the natural or intended direction of flow
Suction; backwash; junction box; fuse box
The flow of electric current in a circuit expressed in amperes
Amperage
A type of low resistance resistor that acts as a sacrificial device to provide overcurrent protection, of either the load or source circuit
Fuse
These act to reduce current flow, and, at the same time, act to lower voltage levels within circuits.
Resistors
The strength of an electric current in amperes
Amperage
An electrical quantity that measures how the device or material reduces the electric current flow through it. It is measured in units of ohms (Ω). If we make an analogy to water flow in pipes, it is bigger when the pipe is thinner, so the water flow is decreased.
