Sample Vidyut Sahayak (Pareshan) Contractual Practice Questions

Try these sample questions to test your Vidyut Sahayak (Pareshan) Contractual exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which of the following mathematical equations represents Ohm's Law in DC circuits?

A.V = I * R

B.V = I / R

C.V = I^2 * R

D.V = P / I^2

Explanation: Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage across it, provided all physical conditions remain constant. Mathematically, V = I * R. The other options are incorrect relationships.

2What is the SI unit of electrical resistivity of a conductor?

A.Ohm-meter

B.Ohm/meter

C.Mho/meter

D.Siemens

Explanation: Resistivity (ρ) is defined as R * A / L, where R is resistance in ohms, A is area in square meters, and L is length in meters. Thus, its unit is Ohm-meter (Ω·m). Mho/meter and Siemens represent conductivity units.

3Two resistors of 10 ohms and 15 ohms are connected in parallel. What is the equivalent resistance of this parallel combination?

A.6 ohms

B.25 ohms

C.12 ohms

D.8 ohms

Explanation: For parallel resistors, the equivalent resistance R_eq is given by (R1 * R2) / (R1 + R2). Here, R_eq = (10 * 15) / (10 + 15) = 150 / 25 = 6 ohms.

4Kirchhoff's Current Law (KCL) at a junction in a circuit is based on the law of conservation of which quantity?

A.Charge

B.Energy

C.Momentum

D.Magnetic Flux

Explanation: Kirchhoff's Current Law states that the total current entering a junction must equal the total current leaving it. This is a direct consequence of the conservation of electric charge, as charge cannot accumulate at a node.

5Which formula is used to calculate the total active power in a balanced three-phase star-connected AC system?

A.P = sqrt(3) * V_L * I_L * cos(theta)

B.P = 3 * V_L * I_L * cos(theta)

C.P = sqrt(3) * V_P * I_P * cos(theta)

D.P = V_L * I_L * cos(theta)

Explanation: Active power in a balanced 3-phase star or delta system is given by P = sqrt(3) * V_L * I_L * cos(theta), where V_L is line voltage and I_L is line current. In terms of phase values, it is P = 3 * V_P * I_P * cos(theta).

6Which electrical testing instrument is specifically designed to measure high insulation resistance, such as that of cables or motor windings?

A.Megger

B.Multimeter

C.Wattmeter

D.Earth Tester

Explanation: A Megger (megohmmeter) is a specialized portable instrument used to measure very high resistances, typically in the megohm range, to evaluate insulation integrity. Multimeters measure lower resistances and voltages, whereas earth testers measure ground electrode resistance.

7What is the SI unit of magnetic flux?

A.Weber

B.Tesla

C.Henry

D.Ampere-turn

Explanation: The SI unit of magnetic flux is the Weber (Wb). Tesla is the unit of magnetic flux density (Weber per square meter), Henry is the unit of inductance, and Ampere-turn is the unit of magnetomotive force (MMF).

8The direction of dynamically induced electromotive force (EMF) in a generator armature conductor is determined by which rule?

A.Fleming's Right-Hand Rule

B.Fleming's Left-Hand Rule

C.Lenz's Law

D.Maxwell's Corkscrew Rule

Explanation: Fleming's Right-Hand Rule is used to determine the direction of induced EMF in a conductor moving through a magnetic field (generator action). Fleming's Left-Hand Rule is used for motors to find the direction of force.

9A capacitor holds a charge of 0.02 Coulombs when connected across a 100V DC source. What is the capacitance of this capacitor?

A.200 microfarads

B.20 microfarads

C.2000 microfarads

D.2 microfarads

Explanation: Capacitance C is calculated as C = Q / V, where Q is charge and V is voltage. Here, C = 0.02 / 100 = 0.0002 Farads, which is equal to 200 microfarads (200 * 10^-6 F).

10Lenz's Law, which defines the direction of induced electromagnetic force, is a direct consequence of which conservation law?

A.Energy

B.Charge

C.Mass

D.Momentum

Explanation: Lenz's Law states that the induced current always flows in such a direction that it opposes the change that produced it. This ensures that work must be done to induce the current, thus obeying the law of conservation of energy.
