Sample Questions and Answers

Question 1. According to the National Electrical Code (NEC), what is the primary purpose of grounding an electrical system?

A. To increase voltage

B. To provide a safe path for fault current

C. To reduce electrical consumption

D. To improve lighting efficiency

Correct Answer: B. To provide a safe path for fault current.

Explanation:
Grounding is one of the most important safety features in an electrical system. It provides a low-resistance path for fault current to travel safely to the ground, helping protective devices such as circuit breakers or fuses operate quickly. This reduces the risk of electric shock, fire, and equipment damage. A licensed electrician must understand grounding requirements and know how they protect both people and property. Questions about grounding and bonding frequently appear on journeyman electrician licensing exams because they are essential for safe electrical installations and compliance with the National Electrical Code (NEC).

Question 2. What does Ohm’s Law calculate when current and resistance are known?

A. Frequency

B. Voltage

C. Power factor

D. Capacitance

Correct Answer: B. Voltage.

Explanation:
Ohm’s Law explains the relationship between voltage, current, and resistance in an electrical circuit. When the current and resistance are known, voltage can be calculated using the formula V = I × R. Understanding this relationship allows electricians to troubleshoot circuits, verify proper operation, and solve many electrical calculation problems. Ohm’s Law is one of the most frequently tested topics on journeyman electrician exams because it serves as the foundation for many electrical principles used in residential, commercial, and industrial electrical systems.

Question 3. Which device is designed to protect a circuit from excessive current?

A. Transformer

B. Circuit breaker

C. Receptacle

D. Conduit

Correct Answer: B. Circuit breaker.

Explanation:
A circuit breaker protects electrical circuits by automatically disconnecting power when excessive current flows through the circuit. This may occur because of an overload, short circuit, or ground fault. By interrupting the flow of electricity, the breaker helps prevent overheating, equipment damage, and electrical fires. Electricians must understand how overcurrent protection devices operate and where they are required by the NEC. Questions about circuit breakers, fuses, and overcurrent protection are commonly included on journeyman electrician licensing examinations because they are critical for electrical safety.

Question 4. Why is conduit commonly used in electrical installations?

A. To increase electrical voltage

B. To protect electrical conductors from physical damage

C. To reduce the number of electrical circuits

D. To improve Wi-Fi signals

Correct Answer: B. To protect electrical conductors from physical damage.

Explanation:
Conduit provides mechanical protection for electrical conductors while also helping organize wiring systems. It shields wires from moisture, impact, chemicals, and other environmental hazards that could damage insulation or create unsafe conditions. Different types of conduit are selected based on the installation location and applicable NEC requirements. Electricians must understand conduit types, sizing, and installation methods to ensure safe and code-compliant electrical systems. Conduit installation and wiring methods are important topics on most journeyman electrician licensing exams.

Question 5. Before working on an electrical circuit, what is the safest first step?

A. Touch the wires to check for voltage.

B. Turn off the power and verify that the circuit is de-energized using an approved testing device.

C. Replace the circuit breaker immediately.

D. Disconnect only the neutral conductor.

Correct Answer: B. Turn off the power and verify that the circuit is de-energized using an approved testing device.

Explanation:
Electrical safety begins by disconnecting the power source and confirming that the circuit is no longer energized before starting any work. Simply switching off a breaker is not enough because circuits may still be energized due to incorrect labeling, backfeeding, or other hazards. Using an approved voltage tester verifies that the circuit is safe to handle. Following proper lockout, verification, and safety procedures greatly reduces the risk of electric shock, arc flash injuries, and equipment damage. Safe work practices are emphasized throughout journeyman electrician licensing exams and are essential for every electrical professional.
