1. What is the primary purpose of the National Electrical Code
(NEC)?
A. To establish electrical utility rates
B. To provide practical safeguards for persons and property from
electrical hazards
C. To regulate electrician wages
D. To determine contractor licensing fees
Answer: B. To provide practical safeguards for persons and property
from electrical hazards
Rationale: The NEC is primarily a safety standard intended to protect
people and property from hazards arising from the use of electricity. It
establishes minimum requirements for electrical installations rather
than regulating wages, utility rates, or business fees.
2. In Kansas, who generally has authority to adopt and enforce local
electrical codes?
A. Only the federal government
B. Only the Kansas Department of Labor
C. Local jurisdictions under Kansas home-rule authority
D. The utility company serving the property
,Answer: C. Local jurisdictions under Kansas home-rule authority
Rationale: Kansas is a home-rule state, so local jurisdictions may
adopt and enforce building and electrical requirements within their
authority. A master electrician must therefore verify the requirements
of the specific Kansas city or county where work is performed.
3. Which NEC article contains general requirements for electrical
installations and conductors?
A. Article 90
B. Article 100
C. Article 110
D. Article 200
Answer: C. Article 110
Rationale: Article 110 contains requirements for electrical
installations, including examination, identification, workmanship,
electrical connections, terminals, and other general installation
provisions.
4. What is the purpose of NEC Article 90?
A. To establish motor requirements
B. To provide the introduction and scope of the NEC
C. To regulate transformers only
D. To establish grounding electrode sizes
Answer: B. To provide the introduction and scope of the NEC
Rationale: Article 90 establishes the purpose, scope, enforcement
concepts, and arrangement of the NEC. It is an important starting
point when learning how the Code is organized.
5. What does the term “ampacity” mean?
,A. The maximum voltage a conductor can withstand
B. The maximum current a conductor can carry continuously under
conditions of use without exceeding its temperature rating
C. The resistance of a conductor
D. The amount of power produced by a generator
Answer: B. The maximum current a conductor can carry
continuously under conditions of use without exceeding its
temperature rating
Rationale: Ampacity is the current-carrying capacity of a conductor
under specified conditions. Proper conductor selection requires
consideration of insulation temperature, ambient temperature,
bundling, installation method, and other applicable correction or
adjustment factors.
6. What is the standard unit used to measure electrical resistance?
A. Volt
B. Ampere
C. Ohm
D. Watt
Answer: C. Ohm
Rationale: Electrical resistance is measured in ohms. Voltage is
measured in volts, current in amperes, and power in watts.
7. Which formula represents Ohm’s law?
A. P = VI
B. V = IR
C. P = I²R
D. E = mc²
Answer: B. V = IR
, Rationale: Ohm’s law states that voltage equals current multiplied by
resistance. This relationship is fundamental to electrical calculations
and troubleshooting.
8. A 120-volt circuit has a resistance of 20 ohms. What current flows
in the circuit?
A. 2 A
B. 4 A
C. 6 A
D. 10 A
Answer: C. 6 A
Rationale: Using I = V/R, the current is 120 ÷ 20 = 6 amperes.
9. What is electrical power calculated as in a DC circuit?
A. P = VI
B. P = V/R
C. P = R/I
D. P = V + I
Answer: A. P = VI
Rationale: Electrical power in watts equals voltage multiplied by
current. For example, a 120-volt load drawing 5 amperes uses 600
watts.
10. A 120-volt load draws 10 amperes. What is its approximate
power?
A. 120 W
B. 600 W
C. 1,200 W
D. 2,400 W
