Q&A| Instant Download Pdf
1. In Maryland jurisdictions that issue a Limited Electrician license, the
primary purpose of the license is generally to:
A. Perform all electrical work without restriction
B. Install nuclear power systems
C. Perform specific categories of electrical work defined by the local
jurisdiction
D. Design utility transmission systems
C. Perform specific categories of electrical work defined by the local
jurisdiction
Rationale: Limited Electrician licenses are typically issued by local
jurisdictions for specific scopes of work and do not grant the broad
authority of a master electrician license.
2. Which publication is the primary standard used for electrical
installation requirements in Maryland?
A. International Plumbing Code
B. National Electrical Code (NEC)
C. International Residential Code only
D. Uniform Mechanical Code
,B. National Electrical Code (NEC)
Rationale: Maryland electrical licensing examinations are based primarily
on the current edition of the National Electrical Code, making NEC
proficiency essential.
3. The main purpose of overcurrent protection is to:
A. Increase voltage
B. Reduce conductor size
C. Protect conductors and equipment from excessive current
D. Improve lighting quality
C. Protect conductors and equipment from excessive current
Rationale: Overcurrent protective devices such as fuses and circuit breakers
prevent damage caused by overloads and short circuits.
4. A conductor carrying current produces:
A. Gravity
B. Magnetism
C. Radiation only
D. Friction
B. Magnetism
Rationale: Electric current flowing through a conductor creates a magnetic
field around the conductor.
5. Ohm’s Law states that voltage equals:
A. Current divided by resistance
B. Resistance divided by power
C. Current multiplied by resistance
D. Power multiplied by current
C. Current multiplied by resistance
, Rationale: Ohm's Law is expressed as V = I × R and is fundamental to
electrical calculations.
6. The unit used to measure electrical resistance is:
A. Watt
B. Volt
C. Ampere
D. Ohm
D. Ohm
Rationale: Resistance is measured in ohms and represents opposition to
current flow.
7. Electrical power is measured in:
A. Watts
B. Volts
C. Ohms
D. Henries
A. Watts
Rationale: Power represents the rate of electrical energy consumption and
is measured in watts.
8. Grounding primarily serves to:
A. Increase load capacity
B. Provide a safe path for fault current
C. Reduce conductor resistance
D. Increase voltage
B. Provide a safe path for fault current
Rationale: Grounding improves safety by helping fault current return to its
source and facilitating protective device operation.
