Displacement current is produced between the plates of a capacitor when potential difference between the plates

A uniform magnetic field (B) is applied between the plates of a capacitor in the outward direction as shown in the figure. Surface charge density on the capacitor plates is sigma . An electron is fired in between the plates, parallel to them, as shown in the figure. The electron is found to move straight in-between the plates of capacitor. Neglect the gravity. If L is the length of the plates then caleulate the time taken by the electron to cross the plates.

(a) A closed loop is held stationary in the magnetic field between the north and south poles of two permanent magnets held fixed. Can we hope to generate current in the loop by using very strong magnets? (b) A closed loop moves normal to the constant electric field between the plates of a large capacitor. Is a current induced in the loop (i) when it is wholly inside the region between the capacitor plates (ii) when it is partially outside the plates of the capacitor? The electric field is normal to the plane of the loop. (c) A rectangular loop and a circular loop are moving out of a uniform magnetic field region (Fig. 6.8) to a field-free region with a constant velocity v. In which loop do you expect the induced emf to be constant during the passage out of the field region? The field is normal to the loops. (d) Predict the polarity of the capacitor in the situation described by Fig. 6.9.

How will the electric field between the plates in parallel plate capacitor change, if the charge on the plates is doubled?

Displacement current is present between the plates of capacitor when the charge on the capacitor is

The electric field (vec( E)) between two parallel plates of a capacitor will be uniform if.

The magnetic field between the circulate plates of radius 12cm separted by distance of 4mm of a parallel plate capacitor of capacitance 100 pF . Along the axis of plates having conduction current of 0.15 A is

A : The displacement current goes through the gap between the plates of a capacitor when the charge on the capacitor does not change. R : Displacement current arises only when the electric field is constant.
