A capacitor is connected to an alternating- current source. Is there a magnetic field between the plates ?

A parallel-plate capacitor is connected to a battery. A metal sheet of negligible thickness is placed between the plates. The sheet remains parallel to the plates of the capacitor.

A parallel plate capacitor is connected to a battery and inserted a dielectric plate between the place of plates then which quantity increase

An uncharged parallel plate capacitor is connected to a battery. The electric field between the plates is 10V/m. Now a dielectric of dielectric constant 2 is inserted between the plates filling the entries space. The electric field between the plates now is

While a capacitor remains connected to a battery and dielectric slab is applied between the plates, then

A parallel plate capacitor is charged to a potential difference V by a dc source. The capacitor is then disconnected from the source. If the distance between the plates in doubled, state with reason how the following will change, (i) electric field between the plates, (ii) capacitance and (iii) energy stored in the capacitor.

A parallel plate capacitor is charged by connecting it to a battery. The battery is disconnected and the plates of the capacitor are pulled apart to make the separation between the plates twice. Again the capacitor is connected to the battery (with same polarity) then the potential difference between the plates increases when the plates are pulled apart (yes or not)

A capacitor only is connected to an AC source. What will be the phase difference between the current flowing in the circuit and the potential difference between the plates of the capacitor?

A bulb B a capacitor C are connected in series to an a.c. source. A dielectric slab is now introduced between the plates of the capacitor. How will the brightness of bulb change ?
