,Question 1
Which electrical principle most accurately explains the relationship between voltage,
current, and resistance in a simple electrical circuit?
A. Kirchhoff's Voltage Law
B. Faraday's Law
C. Ohm's Law
D. Coulomb's Law
Answer: C
Rationale: Ohm's Law states that voltage equals current multiplied by resistance (V =
IR), making it fundamental to electrical calculations.
Question 2
Before climbing any wooden utility pole, what should a journeyman lineman always
perform to help ensure safe working conditions?
A. Energize the line
B. Inspect the pole thoroughly
C. Install a transformer
D. Tighten conductors immediately
Answer: B
Rationale: Pole inspection identifies decay, cracks, insect damage, or instability that
could cause structural failure during climbing.
Question 3
,Why is maintaining the required minimum approach distance from energized
conductors critically important during overhead line work?
A. It reduces equipment costs.
B. It prevents electrical flashover and accidental contact.
C. It improves transformer efficiency.
D. It increases conductor tension.
Answer: B
Rationale: Minimum approach distances protect workers from electrical shock and arc
flash hazards.
Question 4
Which personal protective equipment provides the primary insulation against accidental
electrical contact while performing energized line work?
A. Leather gloves only
B. Rubber insulating gloves with protectors
C. Cotton gloves
D. Mechanic gloves
Answer: B
Rationale: Properly tested rubber insulating gloves are specifically designed to prevent
electrical shock.
Question 5
A three-phase electrical distribution system is generally preferred because it offers
which significant operational advantage over single-phase systems?
, A. Lower efficiency
B. More consistent power delivery and higher capacity
C. Higher resistance
D. Reduced conductor strength
Answer: B
Rationale: Three-phase systems efficiently transmit larger amounts of electrical power
with smoother operation.
Question 6
What is the primary purpose of grounding temporary protective grounds during
maintenance on de-energized electrical lines?
A. Increase voltage
B. Protect workers from accidental energization
C. Improve conductor sag
D. Increase transformer capacity
Answer: B
Rationale: Temporary grounds safely redirect fault current and protect workers if the
circuit becomes unexpectedly energized.
Question 7
Which device automatically interrupts electrical current during excessive fault
conditions to protect distribution equipment?
A. Fuse
B. Transformer
