Introduction

The Rhode Island Telecommunications System Technician (TST) practice exam prepares
candidates for state licensure under the Rhode Island Department of Labor and Training.
This comprehensive assessment evaluates knowledge of Rhode Island General Laws Chapter
5-70, electrical theory, telecommunications infrastructure, network protocols, and safety
standards. The exam employs multiple-choice questions covering regulatory compliance,
technical proficiency, and practical application. Emphasis is placed on the NEC, ANSI/TIA
standards, and the hierarchical licensing structure involving Telecommunications System
Contractors and Technicians. Candidates must demonstrate competency across Data,
Video, Telephony, and Sound categories to achieve the required 70% passing score.

,SECTION ONE: QUESTIONS 1–85

Question 1

What is the primary legal document that defines the three major forms of
telecommunication licenses in Rhode Island?

A. Rhode Island Department of Labor and Training guidelines
B. Rhode Island General Laws, Title 5, Chapter 70
C. The National Electrical Code
D. Federal Communications Commission (FCC) regulations

Correct answer: B. Rhode Island General Laws, Title 5, Chapter 70

RATIONALE: The establishment and definition of the Telecommunications System
Contractor (TSC), Telecommunications Systems Technician (TST), and
Telecommunications System Limited Installer (TSLI) licenses are codified in the Rhode
Island General Laws, specifically Title 5 (Businesses and Professions), Chapter 70
(Telecommunications) .



Question 2

According to Rhode Island law, under what condition must a Telecommunications Systems
Technician (TST) perform their work?

A. Independently, as a licensed professional
B. Under the supervision of a Telecommunications System Contractor (TSC)
C. Under the direct supervision of a Telecommunications System Limited Installer (TSLI)
D. Without any supervision requirement

Correct answer: B. Under the supervision of a Telecommunications System Contractor
(TSC)

RATIONALE: R.I. Gen. Laws § 5-70-5 explicitly states that while a TST license entitles
the holder to perform installation, alteration, servicing, and testing, all work performed
shall be under the supervision of the holder of a TSC license .



Question 3

,A worker is registered with the state as a telecommunications apprentice. What is the
maximum number of such apprentices that can be directly supervised by a single TSC or
TST license holder?

A. One
B. Two
C. Four
D. An unlimited number, as long as they are registered

Correct answer: B. Two

RATIONALE: The Rhode Island General Laws place a clear limit on supervision ratios,
stating that no more than two (2) registered telecommunications apprentices can be
directly supervised by a single TSC or TST license holder .



Question 4

What is the primary function of a resistor in an electronic circuit?

A. To store electrical energy in a magnetic field
B. To regulate the flow of current
C. To amplify a signal
D. To convert alternating current (AC) to direct current (DC)

Correct answer: B. To regulate the flow of current

RATIONALE: A resistor is a passive two-terminal electrical component that
implements electrical resistance as a circuit element. Its primary function is to limit or
regulate the flow of electric current .



Question 5

Ohm's Law is a fundamental principle in electronics. Which equation correctly represents
it?

A. Power = Voltage × Current
B. Voltage = Current × Resistance
C. Current = Resistance × Voltage
D. Resistance = Current × Voltage

Correct answer: B. Voltage = Current × Resistance

, RATIONALE: Ohm's Law defines the relationship between voltage (V), current (I), and
resistance (R) in a linear circuit. The law is mathematically expressed as V = I × R .



Question 6

In a series circuit, if you have three resistors with values of 10 ohms, 20 ohms, and 30 ohms,
what is the total resistance?

A. 10 ohms
B. 20 ohms
C. 60 ohms
D. 6000 ohms

Correct answer: C. 60 ohms

RATIONALE: In a series circuit, the total resistance is the arithmetic sum of all
individual resistances. 10 Ω + 20 Ω + 30 Ω = 60 Ω .



Question 7

Which electronic component is known for allowing current to flow easily in only one
direction and blocking it in the opposite direction?

A. Transistor
B. Capacitor
C. Diode
D. Resistor

Correct answer: C. Diode

RATIONALE: A diode is a semiconductor device that acts as a one-way valve for
current. This property, called rectification, is fundamental for converting AC to DC .



Question 8

Which Rhode Island state agency administers the TST license program?

A. Rhode Island Department of Health
B. Rhode Island Contractors' Registration Board (under Department of Business
Regulation)
