Building Electrical Circuits and Components Flashcards
a complete conducting path carrying current from a source of electricity to and through some electrical device or load and back to the source
Electrical Circuit
a path for electric current
Electrical Circuit
a type of circuit that is complete and has continuous path
Closed Circuit
a type of circuit that is broken, incomplete, and disconnected
Open Circuit
a type of circuit which some current flows through all components of the circuit and the circuit has only one path to take
Series Circuit
a type of circuit which the components are arranged so that the current divides between them; EACH component is assured a charge.
Parallel Circuit
a type of circuit where its condition resulting from bridging any part of a circuit with a conductor of very low resistance.
Short Circuit
this is anything that uses some of the power from the cell
Resistor
these are types of wires and wire insulators
Conductors
materials or substance which allow electricity to flow through them
Conductors
have free electrons on its surface which allow current to pass through easily
Conductors
allow the transmission of heat or light from one source to another
Conductors
an ideal conductor
Metal
the best conductors are precious metals such as?
- silver
- gold
- platinum
the most used materials for conductors?
Copper and Aluminum
AWG stands for?
American Wire Gauge
a single insulated conductors, No. 8 AWG or smaller
Wires
B&S Gauge stands for?
Browne and Sharpe Gauge
- insulated conductors, No. 6 or larger
- may be several conductors of any size assembled into a single unit
- either solid or stranded
Cables
a type of conductors which are not circular in cross section and usually found only to supply the main switch boards
Bus Bars
a conductor current carrying capacity
Ampacity
the maximum operating temperature that its insulation can stand continuously
Conductor Ampacity
generated as a result of the current flowing and the conductor resistance
Heat
type of cable that is fabricated assembly of insulated conductors enclosed in flexible metal sheath
Armored Cable
type of cable that is assembled of one or more conductors each individually insulated enclosed in a metal sheath of interlocking tape of a smooth corrugated tube
Metal Clad Cable
factory assembled conductors insulated with a highly compressed refractory mineral insulation enclosed in a liquid and gas tight continuous copper sheath
Mineral Insulated Cable
- also known for its trade name ROMEX
- two or more insulated conductors having a moisture resistant, flame retardant, and non-metallic material outer sheath
Non-Metallic Sheathed Cable
type of cable where an extruded core of moisture resistant and flame-retardant material covered within an overlapping spiral metal tape
Shielded Non-Metallic Sheathed Cable
a type of cable used for underground connections including direct burial in the ground as a feeder or branch circuit
Underground Feeder
a type of cable that is formed integrally with an insulating material web designed specially for field installation in square structural channels
Flat Cable Assemblies
a type of cable that consists of three or more flat copper conductors placed edge to edge separated and enclosed within a insulating assembly
Flat Conductor Cable
a type of cable provided with or without an overall covering primarily used for service wire
Service Entrance Cable
a type of cable that are used for installation in cable trays, raceways, or where supported by wire.
