Journeyman 1-3 Electrical Exam/ Practice Questions
with Correct Verified Answers/ Latest 2026
1. Electrical Energy can be generated. Which of the following
statements is true?
A) Electricity can be generated
B) Electrical Energy can be generated
C) Both electricity and electrical energy can be generated
D) Neither electricity nor electrical energy can be generated
Answer: B
Rationale: Electrical energy can be generated from other forms of
energy (mechanical, chemical, etc.), while electricity is the flow of
electrons. Energy is generated; electricity is produced .
2. A general term including materials, fittings, devices,
appliances, fixtures, apparatus, and the like used as part of, or
in connection with, an electrical installation is ______.
1
,A) Premises wiring (system)
B) Service equipment
C) Utilization equipment
D) Equipment
Answer: D
Rationale: The NEC defines "equipment" as a general term
including material, fittings, devices, appliances, fixtures, apparatus,
and similar items used in connection with an electrical installation .
3. The permanent joining of metallic parts to form an electrically
conductive path that will ensure electrical continuity and the
capacity to conduct safely any current likely to be imposed is
known as ______.
A) Ordinary tap joint
B) Scarf joint
C) Britannia joint
D) Bonding
2
,Answer: D
Rationale: Bonding is the permanent joining of metallic parts to
form an electrically conductive path that ensures electrical
continuity and the capacity to safely conduct any current likely to
be imposed .
4. An instrument used to measure the diameter of a wire or cable
to thousandths of an inch is a _____.
A) Galvanometer
B) Micrometer
C) Hydrometer
D) Ruler
Answer: B
Rationale: A micrometer is an instrument that accurately measures
the diameter of wire or cable to thousandths of an inch. A
galvanometer measures current, and a hydrometer measures
specific gravity .
3
, 5. What is the resistance at the point of contact of two
conductors or one conductor and another surface?
A) Conductor resistance
B) Contact resistance
C) Resistance per M/ft
D) Resistance per K/ft
Answer: B
Rationale: Contact resistance is the resistance at the point of
contact between two conductors or between a conductor and
another surface. This resistance can create heat and voltage drops
at connections .
6. A value assigned to a circuit or system for the purpose of
conveniently designating its voltage class is _____.
A) Nominal voltage
B) Voltage to ground
