Below a certain critical temperature, superconductors exhibit the Meissner phenomenon, in which the superconductor expels all magnetic fields. Check the attributes of each option in the question to see which one matches the superconductors. Ferromagnetism: A ferrimagnetic material has atom populations with opposing magnetic moments, the opposing moments are uneven, and a spontaneous magnetization remains. As a result, the characteristics do not correspond to those of superconductors. Ferromagnetism is the fundamental process by which some materials produce permanent magnets. Ferromagnetism is the strongest form and is responsible for the frequent occurrence of magnetism found in magnets. As a result, the characteristics do not correspond to those of superconductors. Paramagnetism is a kind of magnetism in which some materials are weakly attracted by an externally applied magnetic field, causing magnetic fields to be produced in the direction of the applied magnetic field. The properties of paramagnetic materials do not correspond to those of superconductors. Diamagnetism: Diamagnetic materials reject magnetic fields; an applied magnetic field induces an induced magnetic field in them in the opposite direction, resulting in a repulsive force. As a result, the characteristics of superconductors correspond to the features of diamagnetism.

In a current-carrying wire, the current is constant throughout the length of the wire, even if the cross-section of the wire changes. This is due to the conservation of charge, which ensures that the same amount of charge flows through any cross-sectional area of the wire per unit of time. The electric field and drift speed depend on the cross-sectional area of the wire and may vary along its length if the wire has a non-uniform cross-section. Thus, only the current remains constant throughout the length of the wire.

Step 1: Understanding the Question:
The question evaluates theoretical knowledge regarding how temperature affects the electrical resistivity of different classes of materials (conductors and semiconductors). Step 3: Detailed Explanation: Analysis of Statement I:
Resistivity ( ) of a conductor (metal) depends on temperature as:
where is the temperature coefficient. For conductors, is positive. As temperature increases, thermal vibrations of lattice ions increase, causing more frequent collisions with electrons. This increases resistance and resistivity. Therefore, Statement I is false. Analysis of Statement II:
For semiconductors, the temperature coefficient of resistivity is negative. As temperature increases, more valence electrons gain enough thermal energy to jump into the conduction band, significantly increasing the charge carrier density ( ). This effect outweighs the increase in lattice scattering. Consequently, the resistivity decreases. Therefore, Statement II is true. Step 4: Final Answer:
Statement I is false but Statement II is true, which corresponds to option (4).

Correct Option:

Step 1: Understanding the Question:
Ohm's law states that the current passing through a conductor is directly proportional to the potential difference across it, provided physical conditions remain constant ( ). To verify this experimentally, we need to measure both current and voltage across a known resistor. Step 3: Detailed Explanation:
To correctly measure electrical parameters in a circuit:
1. Ammeter (A): It measures the current ( ) and must be connected in series with the circuit components to ensure the same current flows through it.
2. Voltmeter (V): It measures the potential difference ( ) and must be connected in parallel across the resistor.
3. Polarity: The positive terminal ( ) of both the ammeter and voltmeter must be connected towards the positive terminal of the power source (battery/cell). Analyzing the provided circuit options:
- In Figure (1), the ammeter is in series and the voltmeter is in parallel. Tracing from the battery's positive terminal (the long line on the right), the current flows through the rheostat and enters the right side of the resistor. The positive terminal of the voltmeter is correctly on the right. Current leaves the left side of the resistor and enters the ammeter's positive terminal at the bottom. This configuration is correct.
- In Figure (2), the voltmeter's polarity is reversed ( is incorrectly on the left).
- In Figures (3) and (4), the ammeter is incorrectly placed in parallel across the resistor and the voltmeter is incorrectly placed in series. Step 4: Final Answer:
The correct circuit for verification of Ohm's law is shown in Figure (1).

4
80C
Official Solution
Correct Option:
(2)
Step 1: Understanding the Question:
The total charge flowing through a circuit component is equal to the area under its current-time ( ) graph. Step 2: Key Formula or Approach:
The charge is given by the definite integral of current over time:
Geometrically, this corresponds to the area of the region between the graph and the time axis. Step 3: Detailed Explanation:
The provided graph forms a right-angled triangle with the following dimensions:
- Base ( ) = 4 s
- Height (initial current ) = 10 A
The area of a triangle is calculated using the formula:
Substituting the values:
Step 4: Final Answer:
The total charge flowing through the wire is 20C.
