To pass the NETA_2 exam, you must put in a lot of time studying, practicing, and working hard. You will need real NETA NETA_2 Questions and the necessary understanding of the exam's format to pass the NETA_2 test. Without preparing with actual NETA Level 2 Certified Assistant Electrical Testing Specialist (NETA_2) questions, applicants find it difficult to get the knowledge essential to pass the NETA certification exam in a short time.
NEW QUESTION # 99
Arc-flash incident energy is expressed in:
Answer: C
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 # 100
Evaluate the expression:
Answer: B
Explanation:
Exponentiation applies to both numerator and denominator:
NETA Level 2 technicians are expected to demonstrate basic mathematical competency for interpreting test data and calculations.
NEW QUESTION # 101
During charging of lead-acid batteries, whichexplosive gasmay be generated?
Answer: B
Explanation:
Hydrogen gas is produced during battery charging due to electrolysis of water in the electrolyte. Hydrogen is highly explosive at relatively low concentrations. NETA Level 2 technicians must ensure adequate ventilation, eliminate ignition sources, and follow battery safety procedures during testing and maintenance.
NEW QUESTION # 102
A series circuit contains two resistors. One resistor dissipates 10 W and the other dissipates 15 W. What is the total power dissipation?
Answer: B
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 # 103
For aDielectric Absorption Ratio (DAR)test on a transformer, the 1-minute insulation resistance value is divided by the value obtained at:
Answer: B
Explanation:
The Dielectric Absorption Ratio (DAR) is defined as:
DAR = IR at 60 seconds ÷ IR at 30 seconds
This test evaluates insulation quality by observing how resistance increases as polarization effects develop.
NETA Level 2 technicians use DAR testing as a quick diagnostic tool, particularly when full polarization index (PI) testing is not practical.
