Electrician license.
MULTIPLE CHOICE.
Section 1: General Knowledge (10 Questions)
1. Which law relates voltage, current, and resistance in an
electrical circuit?
A. Faraday's Law
B. Ohm's Law
C. Kirchhoff's Voltage Law
D. Ampere's Law
Correct answer: B. Ohm's Law
, Page 2 of 56
Rationale: Ohm's Law states that V = I × R, where voltage (V) is the
product of current (I) and resistance (R). This is a fundamental
relationship in electrical theory.
2. What is the term for the maximum current an electrical
conductor can carry without exceeding its temperature rating?
A. Voltage drop
B. Ampacity
C. Resistance
D. Power factor
Correct answer: B. Ampacity
Rationale: Ampacity is defined as the maximum current, in
amperes, that a conductor can carry continuously under the
conditions of use without exceeding its temperature rating.
3. Which NEC Article defines the term "grounded conductor"?
A. Article 100
B. Article 200
C. Article 250
D. Article 310
Correct answer: A. Article 100
Rationale: Article 100 of the NEC contains definitions, including the
definition of a "grounded conductor" (a system or circuit conductor
that is intentionally grounded).

4. In a schematic drawing, what symbol typically represents a
resistor?
A. A circle with "R" inside
B. A zigzag line
C. A straight line with an arrow
D. A series of dots
Correct answer: B. A zigzag line
Rationale: Resistors are typically represented by a zigzag line in
electrical schematics.
5. Which fundamental electrical quantity is measured in volts?
A. Resistance
B. Voltage
C. Current
D. Power
Correct answer: B. Voltage
Rationale: Voltage is the electrical potential difference between two
points and is measured in volts.
6. A continuous load is a load where the maximum current is
expected to continue for a minimum of how many hours?
A. 1 hour
B. 2 hours
C. 3 hours
D. 4 hours
, Page 4 of 56
Correct answer: C. 3 hours
Rationale: NEC Article 100 defines a continuous load as a load
where the maximum current is expected to continue for 3 hours or
more.
7. What is the primary purpose of a one-line diagram?
A. To show detailed mechanical layout
B. To illustrate the interconnection of electrical equipment
C. To provide architectural details
D. To calculate power factor
Correct answer: B. To illustrate the interconnection of electrical
equipment
Rationale: A one-line diagram simplifies the electrical distribution
system by showing how equipment is interconnected.
8. In a dwelling unit living room, receptacles must be installed so
that no point measured horizontally along the floor line in any
wall space is more than how far from a receptacle outlet?
A. 4 feet
B. 6 feet
C. 8 feet
D. 12 feet
Correct answer: B. 6 feet
Rationale: NEC 210.52(A)(1) requires that receptacle outlets be
installed so that no point measured horizontally along the floor line
