ARIZONA CR-67 CONTRACTOR LICENSE – COMPLETE PRACTICE EXAM
300 Questions with Verified Answers and Detailed Rationales
EXAM COVERAGE SUMMARY
This comprehensive 300-question practice exam covers the full scope of the Arizona CR-67 Low
Voltage Communication Systems Contractor License examination. Topics include electrical
fundamentals and theory (Ohm's Law, AC/DC, series and parallel circuits); National Electrical
Code (NEC) requirements (Articles 725, 760, 800, 820, grounding and bonding, conductor sizing,
overcurrent protection); low-voltage communication systems (telephone, data, intercom, PA,
fire alarms, security alarms, access control); wiring methods and raceways; grounding and
bonding; fire alarm systems and NFPA 72; Arizona statutes and rules (contract modifications,
licensing requirements, lien laws, ROC regulations); safety standards and work practices; system
design and troubleshooting; and business management. The exam emphasizes code
compliance, practical knowledge, and regulatory understanding required for successful CR-67
licensing.

SECTION I: ELECTRICAL FUNDAMENTALS (Questions 1–75)
1. Alternating Current (AC) always flows one way then the other?
A. True
B. False
Answer: A
Alternating current (AC) periodically reverses direction, flowing first in one direction and then
the opposite direction. This is distinguished from direct current (DC), which flows in only one
direction.

2. The frequency of AC is measured in what unit?
A. Volts
B. Amperes
C. Hertz
D. Watts
Answer: C
The frequency of AC is measured in hertz (Hz), representing the number of complete cycles per
second.
3. What refers to a voltage that can convey information?
A. Amplitude
B. Electrical Signal
C. Frequency
D. Resistance
Answer: B
3
SUCCESS!
, Page 4 of 158
An electrical signal is a voltage or current that conveys information, typically varying in
amplitude, frequency, or phase to represent data.
4. What refers to the maximum voltage that can be reached by a signal?
A. Frequency
B. Amplitude
C. Phase
D. Wavelength
Answer: B
Amplitude is the maximum voltage (or current) reached by a signal, measured from the zero
reference point to the peak of the waveform.
5. What is the amount of voltage measured between any two line conductors of a balanced
three-phase system?
A. Phase Voltage
B. Line Voltage
