Electricity - ANSWER✔✔Energy used to run household appliances and industrial
machinery; can produce light, sound, heat and numerous other uses.

Current - ANSWER✔✔flow of electricity through a circuit; either AC or DC.

Alternating Current (AC) - ANSWER✔✔electric current reversing its direction of
flow at regular intervals. For example, it would alternate 60 times every second in
a 60-cycle system. This type of current is commonly found in homes.

Direct Current (DC) - ANSWER✔✔electric current flowing in one direction. This
type of current is commonly found in industries.

Ampere - ANSWER✔✔unit used in measuring intensity of flow of electricity.
Symbol for it is "I"

Volt - ANSWER✔✔unit for measuring electrical pressure or force, known as
electromotive force. Symbol for it is "E" or "V".

Watt - ANSWER✔✔unit of electric power. Volt X Ampere = _____.

Circuit - ANSWER✔✔flow of electricity through 2 or more wires from the supply
source to 1 or more outlets and back to the source.

Circuit Breaker - ANSWER✔✔safety device used to break the flow of electricity
by opening the circuit automatically in the event of overloading, or used to open or
close it manually.

Short Circuit - ANSWER✔✔break in the flow of electricity due to overcurrent
resulting from a fault of negligible impedance between live conductors having a
difference in potential under normal operating conditions.

Conductor - ANSWER✔✔any substance capable of conveying an electric current.
In the home, copper wire is usually used.

, Bare Conductor - ANSWER✔✔wire or cable with no insulation or covering.

Covered Conductor - ANSWER✔✔wire or cable covered with 1 or more layers of
insulation.

Fuse - ANSWER✔✔safety device that cuts off the flow of electricity when the

Ground - ANSWER✔✔to connect with the earth as to ground an electric wire
directly to the earth or indirectly through a water pipe or some other conductor.
Usually a green-colored wire is used for grounding the whole electrical system to
the earth. A white wire is usually used to ground individual electrical components
of the whole system.

Conductor Gauge - ANSWER✔✔numerical system used to label electric
conductor sizes, given in American Wire Gauge (AWG) or square-millimeters
(mm2 ) diameter.

Wires - ANSWER✔✔conductors carrying the electric current or power to the load;
usually black or red.

Cable - ANSWER✔✔conductors insulated from one another.

Service - ANSWER✔✔conductor and equipment for delivering energy from the
electricity supply system to the wiring system of the premises.

Service Drop - ANSWER✔✔overhead service connectors from the last pole or
other aerial support to and including the splices, if any, connecting to the service
entrance conductors at the building or other structure.

Insulator - ANSWER✔✔material that will not permit the passage of electricity.

Neutral Wire - ANSWER✔✔third wire in a 3-wire distribution circuit; it is usually
white or light gray and is connected to the ground.
