ANSWERS ALREADY PASSED
◉ define an electrical current. Answer: when electrical pressure is
applied across the length of wire, the free electrons in the wire give up
their random motion and move or flow in one general direction.
◉ define a conductor. Answer: materials having free electrons
◉ define an insulator. Answer: material having few free electrons
◉ what are three examples of good insulators?. Answer: glass, porcelain,
rubber
◉ what is the unit of electric current?. Answer: ampere/amp
◉ what instrument is used to measure electric current. Answer: ammeter
◉ what is the unit of electric pressure?. Answer: voltage
,◉ what is the unit of electric power?. Answer: watt
◉ what is the unit of electric energy?. Answer: watts
◉ what instrument is used to measure electric energy?. Answer:
voltmeter
◉ what is the formula for ohms law?. Answer: V=IxR
(voltage=CurrentxResistance
◉ definition of alternating current. Answer: electric current which
periodically passes through a regular succession of changing values,
both positive and negative
◉ what is the unit of an alternating-current frequency?. Answer: hertz
◉ define the power factor of an alternating-current curcuit. Answer: the
ratio of the actual power to the product of volts times amperes
PF=watts/VoltsxAmperes
◉ describe the theory of operation of an electric transformer. Answer:
voltage must be stepped up and then must be stepped down. the
transformer is the apparatus used to make these changes
, ◉ describe a typical electric system. Answer: powerplant, transmission,
transmission lines, substation, distribution
◉ what is a transmission line?. Answer: a set of conductors energized at
over 69,000 volts and transmitting large blocks of electrical energy over
relatively long distances
◉ how do voltage levels of transmission, subtransmision, and
distribution differ?. Answer: transmission circuits: 69kv-765kv,
subtransmission
◉ when is a direct current transmission line used?. Answer: to transmit
large amounts of power over long distances or to interconnect two AC
systems that are not synchronized
◉ list of functions that can be accomplished in an electric substation.
Answer: switch generators, equipment, and circuits or lines in/out of the
system, change AC voltage from on level to another, or changing AC-
>DC or DC->AC
◉ list the component parts of the electrical distribution system. Answer:
(1) distribution substation, (2) distribution feeder circuits, (3) switches,
(4) protective equipment, (5) primary circuits, (6) distribution
transformers, (7) secondaries, and (8) services
