NETA Level 2 Certified Assistant Electrical Testing Specialist Sample Questions (Q81-Q86):

NEW QUESTION # 81
Which of the following equations correctly represents the relationship betweencapacitance (C),charge (Q), andvoltage (V)?

Answer: A

Explanation:
Capacitance is defined as the amount of electric charge stored per unit of voltage applied across a capacitor.
Mathematically, this relationship is expressed asC = Q / V, where capacitance is measured in farads, charge in coulombs, and voltage in volts. NETA Level 2 technicians must understand this fundamental relationship when interpreting capacitor test data, evaluating dielectric performance, and understanding how voltage stress affects insulation systems. This equation also underpins energy storage calculations and dielectric stress analysis in power system components.


NEW QUESTION # 82
Why shouldlint-free ragsbe used when cleaning circuit breaker components?

Answer: D

Explanation:
Lint fibers can attract dust, moisture, and contaminants, which may degrade insulation and interfere with mechanical movement. NETA Level 2 technicians are expected to maintain cleanliness during maintenance and testing activities to prevent introducing foreign material that could affect breaker performance or reliability.


NEW QUESTION # 83
Underground service conductors between the service equipment terminals and the service lateral are referred to as:

Answer: B

Explanation:
Service point conductors connect the utility service lateral to the service equipment terminals. Understanding conductor classification is important during inspection, testing, and verification of grounding and bonding systems. NETA Level 2 technicians must correctly identify conductor types to apply appropriate testing and safety requirements.


NEW QUESTION # 84
How many connection points are typically found on a Kelvin bridge used for low-resistance measurements?

Answer: B

Explanation:
A Kelvin bridge, also known as a four-wire resistance measurement device, usesfour connection pointsto accurately measure very low resistances. These consist of twocurrent terminalsand twopotential (voltage) terminals.
This configuration eliminates the effects of lead resistance and contact resistance, which can significantly distort measurements when testing bolted connections, bus joints, and grounding conductors. NETA Level 2 technicians routinely use Kelvin methods when performing low-resistance ohmic measurements during acceptance and maintenance testing.
Using fewer than four terminals would result in inaccurate readings, especially at milliohm or micro-ohm levels. Understanding this principle ensures proper test setup and reliable data interpretation.


NEW QUESTION # 85
Which trigonometric function is equal to theopposite side divided by the hypotenuseof a right triangle?

Answer: B

Explanation:
Thesineof an angle is defined as the ratio of the opposite side to the hypotenuse. Trigonometry is used in power factor analysis, phasor relationships, impedance calculations, and AC circuit analysis. NETA Level 2 technicians must understand these relationships when evaluating voltage, current, and phase angles in testing scenarios.
