NETA Level 2 Certified Assistant Electrical Testing Specialist Sample Questions (Q71-Q76):

NEW QUESTION # 71
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 # 72
An overcurrent relay is connected to a200:5 current transformerand has a pickup setting of4 A secondary.
Whatprimary currentwill cause the relay to operate?

Answer: D

Explanation:
A 200:5 CT has a ratio of40:1. A pickup of 4 A on the secondary corresponds to:
Primary current = 4 A × 40 =160 A
NETA Level 2 technicians must accurately convert CT secondary values to primary quantities when setting, testing, and verifying protective relays. Incorrect ratio interpretation is a common cause of miscoordination and false conclusions during commissioning.


NEW QUESTION # 73
Which terminal set would you expect to find on adigital low-resistance ohmmeter (DLRO)?

Answer: A

Explanation:
DLROs use a four-wire (Kelvin) connection: two current terminals (C1, C2) and two potential terminals (P1, P2). This arrangement eliminates lead and contact resistance from measurements, ensuring accurate low- resistance readings for bolted joints, bus bars, and grounding connections.


NEW QUESTION # 74
Power factor is defined as:

Answer: B

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 # 75
Arc-flash incident energy is expressed in:

Answer: A

Explanation:
Incident energy quantifies thermal exposure from an arc flash and is expressed incal/cm². This value is used to determine PPE requirements and safe work practices.


NEW QUESTION # 76
