A current loop in a magnetic field

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 capacitor of capacitance 12.0 muF is joined to an AC source of frequency 200 Hz . The rms current in the circuit is 2.00 A . (a) Find the rms voltage across the capacitor. (b) Find the average energy stored in the electric field between the plates of the capacitor.

A series R-C circuit is connected to an alternating voltage source . Consider two situations: When capacitor is air filled, When capacitor is mica filled. Current through resistor is i and voltage across capacitor is V then:

A parallel plate capacitor is charged to a potential difference of V volts. After disconnecting the charging battery the distance between the plates of the capacitor is increased using an insulating handle. As a result the potential difference between the plates

Find the extra charge given by the battery to the positive plate.

Two thin dielectric slabs of dielectric constants K_1 and K_2 (K_1ltK_2) are inserted between plates of a parallel plate capacitor, as shown in the figure. The variation of electric field E between the plates with distance d as measured from plate P is correctly shown by

A parallel plate capacitor is charged by an exteranl ac source straight the displacement current inside the capacitor is the same as the current charging the capacitor.

A parallel - plate capacitor is being charged.Show that the displacement current across an area in the region between the plates and parallel to it is equal to the conduction current in the connecting wires.
