Sample Haryana BSEH Senior Secondary NSQF Power Practice Questions

Try these sample questions to review concepts for the Haryana BSEH Senior Secondary NSQF Power exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1According to electron theory of electric current in metals, free electrons move mainly under the influence of:

A.Only gravity pulling charges downward

B.An applied electric field that drifts free electrons

C.Nuclear fusion inside the conductor core

D.Sound waves travelling through the wire insulation

Explanation: In metals, loosely bound free electrons form a charge carrier sea. An applied electric field causes a net drift of these electrons, producing electric current.

2Which material group typically has very high resistivity and is used to support or separate live parts?

A.Conductors such as copper and aluminium

B.Insulators such as porcelain, PVC, and glass

C.Superconductors at room temperature only

D.Only pure gold foils

Explanation: Insulators have very few free charge carriers and high resistivity, so they restrict current and are used for supports, bushings, cable sheaths, and barriers.

3A semiconductor at absolute zero of temperature ideally behaves most like:

A.A perfect metal with unlimited free electrons

B.An insulator because valence electrons are tightly bound in the lattice

C.A permanent magnet with no band gap

D.A pure ionic electrolyte

Explanation: At absolute zero, pure semiconductors have essentially no thermally generated free carriers, so they behave like insulators until temperature or doping supplies carriers.

4Ohm’s law for a linear resistor states that:

A.Voltage is proportional to current when temperature and other conditions stay constant

B.Power is always equal to resistance only

C.Current is independent of voltage in all materials

D.Resistance falls to zero whenever voltage rises

Explanation: For ohmic devices, V ∝ I, or V = IR, provided physical conditions such as temperature remain essentially constant.

5A 12 V DC source is connected across a 4 Ω resistor. What is the current?

A.0.33 A

B.3 A

C.48 A

D.16 A

Explanation: Using Ohm’s law, I = V/R = 12/4 = 3 A.

6Three resistors 2 Ω, 3 Ω, and 6 Ω are connected in series across 22 V. The total current is:

A.2 A

B.11 A

C.0.5 A

D.22 A

Explanation: Series resistance Req = 2+3+6 = 11 Ω. I = V/Req = 22/11 = 2 A. Series current is the same through each resistor.

7Two resistors of 6 Ω and 3 Ω are connected in parallel. Equivalent resistance is:

A.9 Ω

B.2 Ω

C.0.5 Ω

D.18 Ω

Explanation: For two parallel resistors, Req = (R1 R2)/(R1+R2) = (6×3)/(6+3) = 18/9 = 2 Ω. Parallel Req is always less than the smallest branch.

8Kirchhoff’s current law (KCL) states that at a circuit node:

A.Algebraic sum of currents entering and leaving is zero

B.Voltage on every branch must be identical always

C.Resistance must equal inductance at resonance only

D.Power is conserved only in open circuits

Explanation: KCL follows charge conservation: the algebraic sum of currents at a node is zero (currents in equal currents out).

9At a junction, currents of 5 A and 3 A enter the node while 2 A leaves. What current must leave on the remaining branch for KCL to hold?

A.6 A

B.10 A

C.0 A

D.1 A

Explanation: Currents in = 5+3 = 8 A. One branch already takes 2 A out, so the remaining outgoing current is 8−2 = 6 A.

10Kirchhoff’s voltage law (KVL) around a closed loop means:

A.Algebraic sum of voltage rises and drops is zero

B.Current is zero in every loop always

C.Only capacitors can appear in a loop

D.Power factor must be unity

Explanation: KVL expresses energy conservation around a loop: the sum of potential differences is zero when polarity signs are applied consistently.

About the Haryana BSEH Senior Secondary NSQF Power Exam

Haryana BSEH Senior Secondary NSQF Power is the Class 12 skill subject (date-sheet code PWR 986) under the Board of School Education Haryana.
