    Let’s analyze the statements:

    Statement I:
    The Supreme Court of India has held in some judgments that reservation policies made under Article 16(4) would be limited by Article 335 to maintain the efficiency of administration.
    This is correct. The Supreme Court, in various rulings (such as the Indra Sawhney case), has emphasized that while Article 16(4) provides for reservations in public employment, it must be balanced with Article 335, which states that the claims of Scheduled Castes and Scheduled Tribes must be consistent with maintaining the efficiency of administration.

    Statement II:
    Article 335 defines the term “efficiency of administration.”
    This is incorrect. Article 335 does not define “efficiency of administration.” It only mentions that the claims of Scheduled Castes and Scheduled Tribes should be taken into consideration, consistent with the maintenance of efficiency of administration. However, it does not provide a definition of “efficiency.”

    Correct answer:
    Statement-I is correct but Statement-II is incorrect

    V=IR

    Description: Ohm’s Law relates voltage
    V    V    , current I, and resistance R in an electrical circuit. It states that the current through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance.

    2. Kirchhoff’s Laws

    (a) Kirchhoff’s Current Law (KCL)

    Statement: The total current entering a junction in a circuit is equal to the total current leaving the junction.

    Description: KCL is based on the principle of conservation of electric charge.

    (b) Kirchhoff’s Voltage Law (KVL)

    Statement: The sum of all the voltages around a closed loop in a circuit is equal to zero. Description: KVL is based on the principle of conservation of energy.

    3. Coulomb’s Law

    Statement:

    F=keq1q2r2F = k_e \frac{q_1 q_2}{r^2}

    Description: Coulomb’s Law describes the electrostatic force between two charged particles. The force is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance between them.

    4. Faraday’s Law of Electromagnetic Induction

    Statement:

    E=βˆ’dΞ¦Bdt\mathcal{E} = – \frac{d\Phi_B}{dt}

    Description: Faraday’s Law states that a change in magnetic flux through a coil induces an electromotive force (EMF) in the coil. This principle is the basis for electric generators, transformers, and inductors.

    5. Lenz’s Law

    Statement: The direction of the induced current (or EMF) is such that it opposes the change in magnetic flux that caused it.

    Description: Lenz’s Law ensures that energy conservation is maintained in electromagnetic systems.

    6. Gauss’s Law

    Statement: The total electric flux through a closed surface is equal to the charge enclosed divided by the permittivity of the medium:

    Ξ¦E=QnecencΞ΅0\Phi_E = \frac{Q_{\text{enc}}}{\varepsilon_0}

    Description: Gauss’s Law explains the relationship between electric charge and electric field.

    7. Conservation of Energy

    Statement: Energy can neither be created nor destroyed, only converted from one form to another.

    Description: In electrical systems, energy is typically converted between electrical, mechanical, and thermal forms, governed by this principle.

    8. Electromagnetic Wave Propagation (Maxwell’s Equations)

    Description: Maxwell’s equations describe how electric and magnetic fields propagate and interact. They govern the behavior of electromagnetic waves, which are essential in communication systems, antennas, and waveguides. The four key equations are:

    • Gauss’s Law for Electricity
    • Gauss’s Law for Magnetism
    • Faraday’s Law of Induction
    • AmpΓ¨re’s Law (with Maxwell’s correction)

    9. Superposition Principle

    Statement: In a linear system, the response caused by two or more stimuli is the sum of the responses that would have been caused by each stimulus individually.

    Description: The principle of superposition is used in the analysis of linear circuits to simplify the study of complex circuits with multiple sources.

    10. Capacitance and Inductance

    (a) Capacitance

    Description: Capacitance is the ability of a system to store electric charge. It is defined by the relationship:

    Q=CV

    ,whereΒ 
    C    C     is the capacitance,
    Q    Q     is the charge, and V is the voltage.

    (b) Inductance

    Description: Inductance is the ability of a conductor to store energy in the form of a magnetic field when current flows through it. The induced EMF is given by:

    E=LdIdt\mathcal{E} = L \frac{dI}{dt}

    , where L is the inductance andΒ 
    I    I     is the current.

    11. Impedance

    Description: Impedance is the opposition to the flow of alternating current (AC) and is the combination of resistance, inductive reactance, and capacitive reactance. Impedance is represented as a complex quantity:

    Z=R+jX

    , where X is the reactance.

     

    12. Power in Electrical Circuits

    (a) DC Power

    P=VI

    , where PΒ  is the power,Β V is the voltage, and IΒ is the current.

    ADHD (Attention-Deficit/Hyperactivity Disorder) is a neurodevelopmental disorder that affects both children and adults. It is characterized by persistent patterns of inattention, hyperactivity, and impulsivity that can interfere with daily functioning and development. Symptoms of ADHD often include difficulty focusing, forgetfulness, trouble following through on tasks, restlessness, and impulsive behavior. There are three main types of ADHD:

    1. Inattentive Type (formerly known as ADD): Characterized primarily by problems with attention and focus, such as difficulty paying attention to details, being easily distracted, or forgetting tasks.
    2. Hyperactive-Impulsive Type: Characterized by excessive fidgeting, inability to stay still, impulsive actions, and talking excessively.
    3. Combined Type: This is the most common form and includes symptoms of both inattentiveness and hyperactivity/impulsivity.

    ADHD is often managed through a combination of behavioral therapy, lifestyle changes, and medication, depending on the severity and individual needs.

    Statement 1 is incorrect because, as per Article 71(2) of the Indian Constitution, the actions performed by a person in the capacity of President or Vice-President remain valid even if their election is declared void by the Supreme Court. Article 71(2) explicitly states that such acts shall not be invalidated due to the court’s declaration. It reads: “If the election of a person as President or Vice-President is declared void by the Supreme Court, acts done by him in the exercise and performance of the powers and duties of the office of President or Vice-President, as the case may be, on or before the date of the decision of the Supreme Court shall not be invalidated by reason of that declaration.”

    Statement 2 is also incorrect. The Constitution of India does not have any provision allowing for the postponement of the Presidential election due to the dissolution of some Legislative Assemblies. The election must be held within the prescribed time, regardless of such dissolutions.

    Statement 3 is incorrect because Article 111 of the Constitution, which outlines the process of granting or withholding assent to bills, does not impose a specific time limit for the President to act on a bill. Article 111 states: “When a Bill has been passed by the Houses of Parliament, it shall be presented to the President, and the President shall declare either that he assents to the Bill, or that he withholds assent therefrom.” There is no mention of a time frame within which the President is required to make this decision. The President may, however, return a non-Money Bill for reconsideration by Parliament, but even here, the Constitution does not set a specific deadline for the President’s assent.
