The natural frequency of an `LC`- circuit is 1,25,000 cycles per second. Then the capacitor `C` is replaced by another capacitor with a dielectric medium of dielectric contant k. In this case, the frequency decreases by 25 kHz. The value of k is

The natural frequency of an LC - circuit is 125KHz. Then the capacitor C is replaced by another capacitor with a dielectric medium of dielectric constant k. In this case, the frequency decreases by 25kHz. The value of k is

The natural frequency of an LC circuit is 125kHz . When the capacitor is totally filled with a dielectric material, the natural frequency decreases by 25kHz . Dielectric constant of the material is nearly.

If C and C_(0) are capacities of a capacitor with and " without dielectric medium respectively then dielectric constant of medium K is

A capacitor of capacitance C is charged to potential difference V and then disconnected from the battery. The air dielectric of capacitor is replaced by another dielectric of dielectric constant K. The fractional decrease in energy of the capacitor is

A parallel plate capacitor has a capacity c. If a medium of dielectric constant K is introduced between plates, the capacity of capacitor becomes

When air is replaced by a dielectric medium of constant K, the maximum capacitance of the capacitor

Show that in parallel plate capacitor, if the medium between the plates of the capacitor is filled with insultaing substance of dielectric contant k, its capacitance increases.

How does the total energy stored by the capacitor change, when the medium of air is replaced by a medium of dielectric constnat K? Explain.
