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:

पर्याय

• displacement current of magnitude equal to I flows in a direction opposite to that of I.

• displacement current of magnitude greater than I flows but can be in any direction.

• there is no current.

• displacement current of magnitude equal to I flows in the same direction as I.

Answer 1

displacement current of magnitude equal to I flows in the same direction as I.

Explanation:

During the capacitor’s charging process through a resistor connected to a battery, the current I primarily flows through the resistor. Similarly, a changing electric field exists between the capacitor plates, which generates a displacement current. According to Ampere’s law with Maxwell’s modification, the displacement current is equivalent in magnitude to the conduction current (I) and travels in the same direction.
