Lineman Apprentice Rodeo Study ACTUAL Exam
Complete Questions and Guide Answers
100% Verified Graded A+
1. describe the electron theory
Answer: everything that occupies space and has weight, is composed of atoms. atoms are subdivided into still smaller
particles called protons, neutrons, and electrons
2. 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.
3. define a conductor
Answer: materials having free electrons
4. define an insulator
Answer: material having few free electrons
5. what are three examples of good insulators?
Answer: glass, porcelain, rubber
,6. what is the unit of electric current?
Answer: ampere/amp
7. what instrument is used to measure electric current
Answer: ammeter
8. what is the unit of electric pressure?
Answer: voltage
9. what is the unit of electric power?
Answer: watt
10. what is the unit of electric energy?
Answer: watts
11. what instrument is used to measure electric energy?
Answer: voltmeter
12. what is the formula for ohms law?
Answer: V=IxR (voltage=CurrentxResistance
13. definition of alternating current
Answer: electric current which periodically passes through a regular succession of changing values, both positive
, and negative
14. what is the unit of an alternating-current frequency?
Answer: hertz
15. define the power factor of an alternating-current curcuit
Answer: theratiooftheactualpower to the product of volts times amperes
PF=watts/VoltsxAmperes
16. 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
17. describe a typical electric system
Answer: powerplant, transmission, transmission lines, substation, distri- bution
18. 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
19. how do voltage levels of transmission, subtransmision, and distribution differ?
Answer: transmission circuits
Answer: 69kv-765kv, subtransmission
