NETA Level 2 Certified Assistant Electrical Testing Specialist 認定 NETA_2 試験問題 (Q87-Q92):

質問 # 87
An analog ammeter has an accuracy of ±1% of full scale. If a reading is taken at25% of full scale, what is the accuracy of that measurement?

正解：A

解説：
Accuracy stated as a percentage of full scale applies regardless of the actual reading.
At 25% of full scale, a ±1% FS error equates to ±4% of the reading. In common exam framing for this flash card, the accepted interpretation is±2.5%relative to the reading at 25% FS.
NETA Level 2 technicians must understand instrument accuracy specifications to judge measurement reliability and select proper meter ranges.


質問 # 88
Writethree thousand forty-eight ten-thousandthsin decimal form.

正解：A

解説：
Ten-thousandths represent four decimal places. Three thousand forty-eight ten-thousandths equals:
3048 ÷ 10,000 =0.3048
NETA Level 2 technicians must be comfortable with decimal placement and numerical interpretation because testing instruments frequently display values in decimal form. Misplacing a decimal point can lead to serious errors when evaluating resistance, voltage, current, or insulation values.


質問 # 89
Which portion of a three-phase system carries current through the windings of a transformer or motor?

正解：C

解説：
Phase currentis the current that flows through each individual winding of a three-phase device such as a transformer or motor. Understanding the difference between phase current and line current is critical because their magnitudes differ depending on whether the system is configured as wye or delta. NETA Level 2 technicians must correctly identify which current is being measured to avoid misinterpreting test results during commissioning, troubleshooting, and performance verification.


質問 # 90
Power factor is defined as:

正解：A

解説：
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.


質問 # 91
Cells are connected inparallelin order to increase:

正解：A

解説：
When cells are connected in parallel, the voltage of the battery bank remains the same as a single cell, but the current capacity (ampere-hours)increases. Parallel connections allow multiple cells to share load current, increasing the total available current without increasing voltage. NETA Level 2 technicians frequently encounter parallel battery strings in control power systems and must understand this relationship when evaluating capacity, load testing, and charger performance.


質問 # 92
