NEET 2024 · PhysicsDisplacement currentPrevious Year Question
A parallel plate capacitor is charged by connecting it to a battery through a resistor. If I is the current in the circuit, then in the gap between the plates,
Answer: (A) Displacement current of magnitude equal to I flows in the same direction as I. Answer: (A) Displacement current of magnitude equal to I flows in the same direction as I.
- A.Displacement current of magnitude equal to I flows in the same direction as I✓
- B.Displacement current of magnitude equal to I flows in a direction opposite to that of I
- C.Displacement current of magnitude greater than I flows but can be in any direction
- D.There is no current
Correct Answer
(A) Displacement current of magnitude equal to I flows in the same direction as I
Solution & Explanation
Answer: (A) Displacement current of magnitude equal to I flows in the same direction as I. To maintain continuity of current, the displacement current between the plates exactly equals the conduction current I in the wires and flows in the same direction, completing the circuit.

PhysTo produce an instantaneous displacement current of 2 mA in the space between the parallel plates of a capacitor of capacitance 4 µF, the rate of change of applied variable potential difference (dV/dt) must bePhysAn ac source is connected to a capacitor C. Due to a decrease in its operating frequency,PhysA capacitor of capacitance C is connected across an ac source of voltage V given by V = V₀ sin ωt. The displacement current between the plates of the capacitor would then be given byPhysA parallel plate capacitor of capacitance 20 µF is being charged by a voltage source whose potential is changing at the rate of 3 V/s. The conduction current through the connecting wires and the displacement current through the plates of the capacitor would be, respectively,PhysAn electric dipole with dipole moment 5 × 10⁻⁶ C·m is aligned with the direction of a uniform electric field of magnitude 4 × 10⁵ N/C. The dipole is then rotated through an angle of 60° with respect to the electric field. The change in the potential energy of the dipole is:PhysTwo identical charged conducting spheres A and B have their centres separated by a certain distance. Charge on each sphere is q and the force of repulsion between them is F. A third identical uncharged conducting sphere is brought in contact with sphere A first and then with B and finally removed from both. New force of repulsion between spheres A and B (radii negligible vs separation, treated as point charges) is best given as:PhysThe plates of a parallel plate capacitor are separated by d. Two slabs of different dielectric constant K1 and K2 with thickness 3d/8 and d/2 respectively are inserted in the capacitor. Due to this, the capacitance becomes two times larger than when there is nothing between the plates. If K1/K2 = 1.25, the value of K1 is:PhysA sphere of radius R is carved out of a uniform solid sphere of radius 2R (internally tangent, so its centre is at distance R from the big centre). The ratio of the moment of inertia of the small sphere to that of the remaining part, both about the Y-axis through the big sphere's centre, is:
