NETA Level 2 Certified Assistant Electrical Testing Specialist Sample Questions (Q16-Q21):

NEW QUESTION # 16
A series circuit contains two resistors. One resistor dissipates 10 W and the other dissipates 15 W. What is the total power dissipation?

Answer: D

Explanation:
In a series circuit (or any circuit),total poweris the sum of the power dissipated by each element. If one resistor dissipates 10 W and the other dissipates 15 W, then:
Total Power = 10 W + 15 W =25 W
NETA Level 2 technicians must be comfortable with basic electrical math because field testing often requires verifying expected values, sanity-checking readings, and confirming that instruments and test setups make sense. Power relationships also appear in evaluating loading, heating, and potential abnormal conditions.
While in many real-world cases you might calculate power using P = VI, P = I²R, or P = V²/R, in this question the element power dissipations are already provided, making the total a straightforward sum.
This concept also supports troubleshooting: if measured losses appear inconsistent with expected totals, it may indicate incorrect metering connections, inaccurate instrument scaling, or problems such as loose connections causing unexpected heating and power loss.


NEW QUESTION # 17
Power factor is defined as:

Answer: C

Explanation:
Power factor is the ratio ofreal power (watts)toapparent power (volt-amperes). This ratio indicates how effectively electrical power is being converted into useful work. NETA Level 2 technicians must understand power factor when evaluating system efficiency, loading, and the impact of reactive components.


NEW QUESTION # 18
A transformer contains insulating fluid with aspecific gravity greater than 1. From where should the oil sample be drawn?

Answer: D

Explanation:
Specific gravity greater than 1 means the insulating fluid isheavier than water. Any free water contamination will settlebelowthe oil. To avoid collecting settled contaminants and to obtain a representative oil sample, NETA practice requires sampling from thetop of the tank.
Correct sampling technique is critical for accurate dielectric, moisture, and dissolved gas analysis results.
NETA Level 2 technicians must understand fluid properties to avoid misleading test conclusions.


NEW QUESTION # 19
Which lubricant is commonly specified for use in bothconductiveandmechanicalareas of circuit breakers and switches?

Answer: C

Explanation:
Circuit breakers and switches include bothcurrent-carrying interfaces(where conductivity and contact integrity matter) andmechanical moving components(where friction, wear, and smooth operation matter).
NETA Level 2 objectives expect technicians to follow manufacturer guidance and industry-accepted practices for cleaning and lubrication during inspection and maintenance activities.
Mobil 28is widely referenced in the industry for breaker and switch applications because it performs reliably over a broad temperature range and provides stable lubrication for mechanical parts while being used in certain conductive interfaces where specified. The key is that lubrication must match the component requirements: too much lubricant, the wrong type, or applying lubricant in inappropriate locations can attract contamination, increase resistance at contacts, or interfere with proper mechanism operation.
WD-40 is not an appropriate precision lubricant for breaker mechanisms. Graphite can be conductive and create unintended paths, and dielectric silicone greases are primarily intended for insulating/anti-moisture applications rather than general breaker conductive/mechanical lubrication unless specifically approved.
In NETA-style work, lubrication is not "generic"-it is controlled by procedure, manufacturer instructions, and the intended function of the surfaces involved.


NEW QUESTION # 20
Determine theRMS voltageof a sinusoidal waveform displayed on an oscilloscope showing 0.45 V peak with a vertical sensitivity of 0.2 V/division.

Answer: C

Explanation:
RMS voltage for a sine wave equals peak voltage divided by #2:
V### = 0.45 ÷ 1.414 #0.32 V
NETA Level 2 technicians must understand RMS values because most electrical measurements and equipment ratings are based on RMS quantities, not peak values.
