Question 1

Watt

Answer 1

(W)

A unit of electrical power

The product of voltage and amperage, total power output

Question 2

Amperage

Amp

Answer 2

(I)
A unit of current.
One ampere will flow through a resistance of 1 (ohm) under a pressure of 1 V. (volt)

Question 3

Volt

Answer 3

(V)

A unit of electrical force.
One volt is required to force 1 A of electricity through a resistance of 1 ohm

Question 4

Fresnel

Answer 4

A type of lens that has the same optical effect as a plano-convex lens, but has reduced weight and heat retention
(A light that uses a fresnel lens)

(Plano-convex: lens, flat on one side, convex on the other.)

Question 5

NEMA

Answer 5

National Electrical Manufacturers Association

Defines standards for connectors, ingress protection for electrical equipment in the US, etc

Question 6

HZ

Answer 6

HZ - AC circuit cycles per second (want to keep it at 60, +/- .2)

Question 7

OSHA

Answer 7

Occupational Safety and Health Administration

Question 8

IATSE

Answer 8

International Alliance of Theatrical AND Stage Employees

Question 9

Single-phase

Answer 9

Any load that is powered from one phase wire and the neutral, or two phase wires.
(Almost all lighting loads are single-phase)

Question 10

Three-phase

Answer 10

Creates alternating current in three leads–the AC cycle of voltage in each lead is a third of a cycle (120 degrees) apart from the last.

A three-phase power source may be used to power single-phase loads of different voltages by using of the phase wires, or one phase wire and a neutral wire.

(A three-phase load is one that requires all three phase wires. Examples of three-phase loads used in lighting include some xenon ballasts, chain motors, Luminy SoftSun, and 480 V step-down transformers.)

Question 11

Ground

grounding wire

Answer 11

the green, noncurrent-carrying equipment grounding wire of an AC circuit

Question 12

Neutral

Grounded wire

Answer 12

The grounded, white, current-carrying wire of an AC circuit

should be mentioned that it’s a return for A/C distrobution system

(Not to be confused with the green “grounding wire”)
