Section 1: Electrical Theory and Ohm's Law Fundamentals (Q1-Q12)
Q1: An elevator constructor apprentice needs to measure the current flowing through a motor circuit. How
should the ammeter be connected to obtain an accurate reading?
A. Connected in parallel across the motor terminals
B. Connected in series with the circuit so that all current flows through the meter
C. Connected across the power supply with the circuit de-energized
D. Connected in parallel with a shunt resistor only
Correct Answer: B. Connected in series with the circuit so that all current flows through the meter
**[CORRECT]**
Rationale: An ammeter must be connected in series with the circuit because it measures the flow of current (amperes)
through a conductor. All current in the circuit must pass through the meter for an accurate reading. Connecting an
ammeter in parallel (A, C, D) would create a low-resistance path across the circuit, potentially damaging the meter and
creating a short circuit. This distinction between series (ammeter) and parallel (voltmeter) connections is a fundamental
safety and measurement concept in the NEIEP 300 curriculum.
Q2: A voltmeter is used to measure the potential difference across a door interlock circuit. What is the correct
connection method for this measurement?
A. Connected in series between the power source and the load
B. Connected in parallel across the component or circuit section being measured
C. Connected in series with the ground conductor only
D. Disconnected from all power sources before taking the reading
Correct Answer: B. Connected in parallel across the component or circuit section being measured
**[CORRECT]**
Rationale: A voltmeter measures potential difference (voltage) and must be connected in parallel across the component or
circuit section of interest. Because voltmeters have very high internal resistance, they draw negligible current and do not
significantly affect circuit operation when placed in parallel. Connecting in series (A, C) would impede current flow and
give meaningless readings. Option D is incorrect because voltage measurements require the circuit to be energized. The
NEIEP 300 curriculum emphasizes proper meter connection as both a measurement accuracy and safety requirement.
Q3: Which unit measures the quantity of electrons passing a given point in a conductor?
A. Volt
B. Ampere
C. Ohm
D. Coulomb
Correct Answer: D. Coulomb **[CORRECT]**
Rationale: The coulomb is the unit of electrical charge and measures the quantity of electrons passing a given point. One
coulomb equals approximately 6.242 x 10 to the 18th electrons. The ampere (B) measures the rate of electron flow
(current), or coulombs per second. The volt (A) measures potential difference (electrical pressure). The ohm (C) measures
resistance. This distinction between charge quantity (coulomb) and current rate (ampere) is a core concept in the NEIEP
300 electrical theory module.

Q4: Using Ohm's Law, a circuit has 30 mA of current flowing through a 600 ohm resistor. What is the voltage
across the resistor?
A. 0.05 V
B. 1.8 V
C. 18 V
D. 20 V
Correct Answer: C. 18 V **[CORRECT]**
Rationale: Using Ohm's Law (E = R x I), first convert 30 mA to amperes: 30 mA = 0.03 A. Then calculate: E = 600 ohms x
0.03 A = 18 V. Option A results from dividing instead of multiplying. Option B results from using 0.003 A instead of 0.03
A. Option D has no mathematical basis. The NEIEP 300 curriculum requires apprentices to be proficient in Ohm's Law
calculations including proper unit conversions between mA and A.
Q5: In a circuit, if the resistance is doubled while voltage remains constant, what happens to the current?
A. Current doubles
B. Current is halved
C. Current remains the same
D. Current quadruples
Correct Answer: B. Current is halved **[CORRECT]**
Rationale: According to Ohm's Law (I = E/R), current is inversely proportional to resistance when voltage is held
constant. If resistance doubles, current is halved. For example, if E = 120V and R increases from 10 ohms to 20 ohms,
current decreases from 12A to 6A. Options A and D describe what would happen if resistance decreased. Option C ignores
the inverse relationship. Understanding the inverse relationship between current and resistance is a foundational
competency in the NEIEP 300 curriculum.
Q6: The power dissipated by a resistor is calculated using P = R x I squared. If a 50 ohm resistor dissipates 2
watts, what is the current flowing through it?
A. 0.04 A
B. 0.2 A
C. 0.5 A
D. 25 A
Correct Answer: B. 0.2 A **[CORRECT]**
Rationale: To find current using the power formula P = R x I squared, rearrange to solve for I: I = the square root of
(P/R). Therefore I = the square root of (2/50) = the square root of (0.04) = 0.2 A. Option A results from P/R without taking
the square root. Option C results from R/P. Option D results from R x P. The NEIEP 300 curriculum requires mastery of
power formula rearrangement for troubleshooting electrical circuits in elevator systems.
Q7: The outermost shell of an atom, which determines the atom's electrical and chemical properties, is called
the:
A. Nucleus
B. Valence shell
C. Electron core
D. Proton layer
