A unifrom current of density f flows inside an infinite plate of thickness 2d parallel to its surface . Find the magentic induction induced by this current as a funcition of the distance x from the median palane of the plate. The magnitude permeability is assumed to be equal to unity both inside and outside the plates.

A dielectric slab of thickness d is inserted in a parallel plate capacitor whose negative plate is at x = 0 and positive plate is at x = 3d . The slab is equidistant from the plates. The capacitor is given some charge. As one goes from 0 to 3d :

A dielectric slab of thickness d is inserted in a parallel plate capacitor whose negative plate is at x=0 and positive plate is at x = 3d . The slab is equidistant from the plates. The capacitor is given some charge. As one goes from 0 to 3d(1998) .

Two parallel-plate capacitors with different distances between the plates are connected in parallel to a voltago source. A poin t posit.ivo charge is moved from a point 1 that is ex aetly j n the midtlle between the plates of a capacitor Cl to a point 2 (or a capacitor C2 ) that lies at a distance from the negative plate of C2 equal to half the distance between the plates of Cl. Is any work done in the process?

Show that the magnetic field B at a point in between the plates of a parallel plate capacitor during charging is (mu_(0)epsilon_(0)r)/(2) (dE)/(dt) (symbols having usual meaing). ,

The plates of a parallel plate capacitor have surface area 'A' and are initially separated by a distance 'd'.They are connected to a battery of voltage v_(0) . Now the plates of the capacitor are pulled apart to a separation 2d .Then,increase in the energy of the battery is
