Question 1: What is the primary unit used to measure electrical current?
A. Volt
B. Ampere
C. Ohm
D. Watt
Answer: B
Explanation: The ampere is the fundamental unit of current in the International System of
Units, representing the rate of electron flow.
Question 2: Which law is fundamental in electrical theory relating voltage, current, and
resistance?
A. Faraday’s Law
B. Coulomb’s Law
C. Ohm’s Law
D. Newton’s Law
Answer: C
Explanation: Ohm’s Law states that the voltage across a conductor is proportional to the
current flowing through it, with the resistance being the constant of proportionality.

Question 3: In AC circuits, which type of reactance occurs due to inductors?
A. Capacitive
B. Resistive
C. Inductive
D. Static
Answer: C
Explanation: Inductive reactance is produced by inductors in AC circuits as they oppose the
change in current.
Question 4: Which unit is used to measure the potential difference in an electrical circuit?
A. Ohm
B. Ampere
C. Volt
D. Watt
Answer: C
Explanation: The volt measures the electrical potential difference between two points.
Question 5: What does the term “ampacity” refer to in conductor sizing?

License Exam
A. Voltage rating
B. Current carrying capacity
C. Resistance value
D. Temperature coefficient
Answer: B
Explanation: Ampacity is the maximum current a conductor can carry safely without
overheating.
Question 6: Which of the following materials is known for its excellent conductivity?
A. Plastic
B. Copper
C. Rubber
D. Wood
Answer: B
Explanation: Copper is highly conductive and is the standard material used for many wiring
applications.
Question 7: What type of circuit has components connected in a single path?
A. Parallel

License Exam
B. Series
C. Combination
D. Branch
Answer: B
Explanation: In a series circuit, the components are connected end-to-end along one path, so
the same current flows through each component.
Question 8: What is the purpose of insulation on electrical conductors?
A. Increase conductivity
B. Protect against corrosion
C. Prevent electrical shock
D. Amplify current
Answer: C
Explanation: Insulation prevents accidental contact with the live conductor, reducing the risk of
electrical shock.
Question 9: Which type of wiring system is enclosed in a protective tube or conduit?
A. Cable
B. Raceways
