Introduction
,This practice test is designed to prepare candidates for electrical licensing examinations in Kentucky
jurisdictions. The exam assesses critical skills including electrical theory application, NEC code compliance,
proper wiring installation methods, grounding and bonding techniques, and overcurrent protection selection.
The assessment features multiple-choice questions and scenario-based problems that emphasize real-world
application and professional decision-making. Candidates will encounter questions requiring calculations, code
references, safety judgments, and ethical considerations relevant to professional electrical work. Success
requires both theoretical knowledge and practical understanding of electrical systems installation and
maintenance according to current industry standards.*
Section One: Questions 1–25
Question 1
What is the current (in amperes) flowing through a 120-volt circuit connected to a 1440-watt resistive load?
A. 8 A
B. 10 A
C. 🟢 12 A
D. 14 A
🔴 RATIONALE: Using the power formula P = V × I, we solve for current: I = P ÷ V = 1440 watts ÷ 120 volts =
12 amperes. This is a fundamental electrical theory calculation required for circuit design and load assessment.
, Question 2
According to Ohm's Law, which equation correctly calculates voltage in an electrical circuit?
A. 🟢 V = I × R
B. V = P ÷ I
C. V = R ÷ I
D. V = I × P
🔴 RATIONALE: Ohm's Law states that voltage (V) equals current (I) multiplied by resistance (R), expressed as
V = I × R. This is the foundational relationship for all electrical circuit calculations and is essential for
determining voltage drops and circuit parameters.
Question 3
What is the total resistance of three 15-ohm resistors connected in parallel?
A. 🟢 5 ohms
B. 15 ohms
C. 45 ohms
D. 3 ohms
