NEW QUESTION # 11
Which of the following equations correctly represents the relationship betweencapacitance (C),charge (Q), andvoltage (V)?
- A. C = Q / V
- B. C = V / Q
- C. V = Q / C²
- D. Q = C × 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 # 12
When making a resistance measurement, which ohmmeter range should be selectedinitially?
- A. Highest resistance range
- B. Auto-range only
- C. Lowest resistance range
- D. Mid-scale range
Answer: C
Explanation:
Starting with thelowest resistance rangeprovides maximum sensitivity and allows the technician to determine whether resistance is within the expected low-ohmic range. This approach supports accurate measurements during continuity testing, bolted-connection checks, and component verification.
NEW QUESTION # 13
Electrical equipment working space must have at least two entrances of sufficient area to permit access.
- A. True
- B. False
- C. True only above 600 V
- D. False unless the room is classified as a confined space
Answer: A
Explanation:
Working space and egress requirements exist to ensure personnel canquickly exitan area in the event of an arc flash, fire, or other emergency. Codes and safety practices commonly requiretwo means of egress(two entrances) when certain conditions are met, particularly when large equipment, high fault current, or certain room layouts increase risk and limit escape paths.
From a NETA Level 2 safety standpoint, the practical takeaway is that equipment rooms must not trap workers. Adequate working clearances and egress routes must be verified as part of safe work planning- especially during commissioning where multiple panels may be open, temporary barriers may exist, and contractors may crowd the space.
While the exact conditions and thresholds can vary by NEC article and equipment rating, the concept tested here matches the flash-card: providing at least two entrances is considered a compliant requirement for safe access to electrical equipment working space in the relevant scenario context.
NEW QUESTION # 14
You arrive to perform acceptance testing on a newly installed indoor 15 kV switchgear lineup. Covers are removed and conductors are exposed with taped ends. What is thecorrect initial action?
- A. Begin insulation resistance testing
- B. Assume the equipment is safe since it is new
- C. Proceed with visual inspection only
- D. Verify the source is de-energized and apply lockout
Answer: D
Explanation:
Before any testing or inspection begins, NETA safety practices require verification of anelectrically safe work condition. Even newly installed equipment may be energized unintentionally or improperly isolated.
Exposed conductors increase the risk of shock and arc flash.
The correct action is tovisually confirm that all sources of power have been de-energized, followed by properlockout/tagoutprocedures. This ensures no unexpected energization can occur during testing activities.
NETA Level 2 technicians must never assume equipment is safe based on installation status. Safety verification always precedes inspection, testing, or commissioning work.
NEW QUESTION # 15

- A. 0.3048
- B. 30.48
- C. 3.048
- D. 0.0348
Answer: A
Explanation:
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.
NEW QUESTION # 16
When personnel are working in apermitted confined space, how many attendants must remain outside the space and for how long?
- A. One attendant, during entry only
- B. Two attendants, until entry permit expires
- C. One attendant, for the duration of the operation
- D. Two attendants, during energized work
Answer: C
Explanation:
Confined space safety requirements mandate thatat least one trained attendantremain outside the spacefor the entire duration of the entry operation. The attendant monitors conditions, maintains communication, and initiates rescue procedures if needed. NETA Level 2 technicians must comply with confined space protocols when testing transformers, vaults, or enclosed switchgear compartments.
NEW QUESTION # 17
What is theRestricted Approach Boundaryfor a69 kVsystem?
- A. 2 ft 2 in
- B. 6 ft 0 in
- C. 1 ft 0 in
- D. 3 ft 10 in
Answer: D
Explanation:
Approach boundaries are central to electrical safety programs aligned with NFPA 70E concepts and the safe work practices expected of NETA technicians. TheRestricted Approach Boundaryrepresents the distance from an exposed energized conductor or circuit part where there is an increased likelihood of shock, requiring specialized training, PPE, and controls. Entry is tightly controlled and generally requires work planning, justification, and protection methods.
For a69 kVsystem, the target Restricted Approach Boundary in your flash cards is3 ft 10 in. This value is used in field safety planning to establish barricades, determine permissible proximity, and ensure that only qualified persons with appropriate protective measures enter that space.
NETA Level 2 technicians must be able to apply boundaries when setting up test areas, especially in switchyards and medium/high-voltage environments, where inadvertent approach can occur during lead placement, phasing, or instrument setup. Correct boundary application is not optional-it is a foundational requirement to prevent shock exposure.
NEW QUESTION # 18
A digital multimeter (DMM), when set to measure voltage, typically has which type of input impedance?
- A. Fixed, high input impedance
- B. Impedance proportional to measured voltage
- C. Variable impedance based on range
- D. Low impedance to improve accuracy
Answer: A
Explanation:
Digital multimeters are designed withhigh, fixed input impedance-typically 10 megohms or higher-when measuring voltage. This minimizes loading effects on the circuit under test and allows accurate measurement without significantly altering circuit conditions.
NETA Level 2 technicians must understand meter characteristics to avoid misinterpretation of readings. High input impedance is especially important when testing control circuits, electronic relays, and high-resistance paths. Unlike analog meters, DMMs do not significantly load the circuit, making them suitable for precise voltage measurements in modern electrical systems.
NEW QUESTION # 19
The three-phase connection in whichone end of each winding is connected togetheris called which configuration?
