QUESTION 1
What is the primary purpose of personal protective equipment (PPE) on an electrical job site?
A. Increase work speed
B. Reduce electrical resistance
C. Protect against workplace hazards
D. Improve tool efficiency
════════════════════
Correct Answer: C. Protect against workplace hazards
Rationale: PPE is designed to minimize exposure to hazards such as electric shock, arc
flash, and physical injury. It does not affect electrical performance or tool efficiency. Options
A, B, and D are unrelated to safety functions.
════════════════════
QUESTION 2
Which law governs electrical safety standards in Alberta for apprentices and journeypersons?
A. National Building Code
B. Canadian Electrical Code (CEC)
C. Alberta Traffic Safety Act
D. Occupational Health and Safety Code
════════════════════
Correct Answer: D. Occupational Health and Safety Code
Rationale: The Occupational Health and Safety Code sets enforceable safety requirements
for electrical work in Alberta workplaces. The CEC governs installation standards but is not a
safety enforcement law.
════════════════════
QUESTION 3
,What unit is used to measure electrical resistance?
A. Ampere
B. Volt
C. Ohm
D. Watt
════════════════════
Correct Answer: C. Ohm
Rationale: Resistance is measured in ohms (Ω), which describes opposition to current flow.
Amperes measure current, volts measure potential difference, and watts measure power.
════════════════════
QUESTION 4
A circuit has a voltage of 120V and a resistance of 30Ω. What is the current?
A. 2A
B. 4A
C. 3A
D. 5A
════════════════════
Correct Answer: B. 4A
Rationale: Using Ohm’s Law (I = V/R), 120 ÷ 30 = 4 amperes. The other options reflect
incorrect division or multiplication errors.
════════════════════
QUESTION 5
What is the main function of a circuit breaker?
A. Increase voltage
B. Store electrical energy
C. Protect against overcurrent
D. Convert AC to DC
,════════════════════
Correct Answer: C. Protect against overcurrent
Rationale: Circuit breakers automatically interrupt current flow during overload or short
circuit conditions, preventing damage and fire hazards.
════════════════════
QUESTION 6
Which tool is used to measure voltage in a circuit?
A. Clamp meter
B. Multimeter
C. Ohmmeter only
D. Insulation tester
════════════════════
Correct Answer: B. Multimeter
Rationale: A multimeter can measure voltage, resistance, and current. While clamp meters
measure current, they are not primarily used for voltage measurement.
════════════════════
QUESTION 7
What is the function of grounding in an electrical system?
A. Increase current flow
B. Provide a safe path for fault current
C. Reduce voltage drop
D. Improve conductor resistance
════════════════════
Correct Answer: B. Provide a safe path for fault current
Rationale: Grounding ensures fault current is safely directed into the earth, reducing shock
and fire risk. It does not increase performance metrics.
════════════════════
, QUESTION 8
Which of the following is a conductor material commonly used in residential wiring?
A. Rubber
B. Copper
C. PVC
D. Glass
════════════════════
Correct Answer: B. Copper
Rationale: Copper is widely used due to its excellent conductivity and durability. Insulating
materials like rubber, PVC, and glass do not conduct electricity.
════════════════════
QUESTION 9
What does a series circuit characteristic include?
A. Multiple current paths
B. Same voltage across all components
C. One continuous path for current
D. Independent branches
════════════════════
Correct Answer: C. One continuous path for current
Rationale: In a series circuit, current flows through a single path. Voltage divides across
components, and there are no branches.
════════════════════
QUESTION 10
What happens if one component fails in a series circuit?
A. Only that component stops working
B. The entire circuit stops working
