NEW QUESTION # 19
A series circuit contains two resistors. One resistor dissipates 10 W and the other dissipates 15 W. What is the total power dissipation?
Answer: C
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 # 20
Following an insulation resistance test on a motor circuit, what procedure is required to safely return the circuit to a neutral charge state?
Answer: A
Explanation:
Insulation resistance testing leaves stored electrical charge in the insulation. NETA standards require grounding the circuit forfour times the duration of the applied test voltageto safely dissipate stored energy.
Failure to do so can result in dangerous shock hazards even after testing is complete.
NEW QUESTION # 21
Which property of an insulating liquid is defined as thelowest temperature at which sufficient vapor is produced to ignite?
Answer: A
Explanation:
Theflash pointindicates the minimum temperature at which an insulating liquid emits enough vapor to form an ignitable mixture with air. This property is critical for safety assessment, handling, and classification of transformer fluids. NETA Level 2 technicians must understand flash point significance when evaluating insulating liquids used in electrical equipment.
NEW QUESTION # 22
Cells are connected inseriesin order to increase:
Answer: B
Explanation:
When electrical cells are connected in series, their individual voltages add together, increasing the overall voltage ratingof the battery string. Current capacity remains the same as that of a single cell.
NETA Level 2 technicians frequently encounter battery banks used for control power, protective relays, and emergency systems. Understanding series versus parallel connections is essential when testing battery voltage, interpreting readings, and diagnosing capacity or voltage issues during commissioning and maintenance.
NEW QUESTION # 23
A control contact that includes one normally open (NO) contact and one normally closed (NC) contact operated by a single actuator is classified as which contact form?
Answer: A
Explanation:
Control contacts are categorized by their functional behavior and internal configuration. AForm C contact consists ofone normally open (NO) and one normally closed (NC) contactthat share a common movable contact and operate together. When the actuator changes state, one contact opens while the other closes.
This configuration is commonly used in control circuits where a change of state must simultaneously initiate one function and terminate another, such as interlocking schemes, status indication, and control logic. NETA Level 2 technicians frequently encounter Form C contacts in relays, auxiliary switches on circuit breakers, and motor control equipment.
Form A contacts are normally open only, while Form B contacts are normally closed only. Form C provides greater flexibility and is widely used in protection and control systems. Correct identification of contact forms is critical during continuity testing, functional verification, and troubleshooting of control circuits.
