A capacitor is charged with a constant current I. Points A and B
are located at a distance that is slightly larger than the radius
of the capacitor plates, measured from the wire and/or the center
of the capacitor. Points C and D are located at a distance that is
smaller than the radius of the capacitor plates, measured from the
wire and/or the center of the capacitor. Rank the magnitude of the
magnetic field at the points A-D from...

A current i flows into (and, on the other side, out of) a paralle-plate capacitor. The plates are circular, spaced 0.0010 m apart, and have an area of 0.785m2. The voltage across the capacitor changes at 1.0 kV/s, causing a magnetic field to be induced in the capacitor, parallel to the plates. (a) Find the rate at which the electric field and the electric flux are changing between the plates. (b) Find the magnitude of the magnetic field between the...

The capacitor plates are circular with radius 1.0 cm and separation 1.0 mm. Again, the magnetic field strength is initially B 0.750 T and subsequently decreases in time at the constant rate -0.035 T/s (a) Sketch a charge diagram illustrating the final charge distribution on the capacitor plates When this final distribution is obtained, what is the...

Compute the magnetic field generated by the displacement current inside a plane place capacitor of area A and separation d. Specifically, assume the plates to be circular and compute the magnetic field in points at a distance r from the axis of the capacitor. Hint: focus on the current density, rather than on the current itself, assuming this to be uniform in the entire volume between the plates of the capacitor.

In a typical parallel plate capacitor the separation distance between the plates is "d". For a charged capacitor, if you increase only the separation distance of the plates the following occurs: The potential (V) between the plates remains constant but the electric field increases, The potential (V) between the plates increases but the electric field remains constant. The potential (V) between the plates remains constant and the electric remains constant. The...
