Dielectric in Capacitor||Examples On Dielectric in Capacitor

Consider a disconnected. Plate capacitor of capacity 10 mu with air filled in the gap between the plates. Now one-half of the space between the plates is filled with a dielectric of dielectric constant 4 as shown in .The capacity of the capacitor changes to .

The radii of a spherical capacitor are 0.5 m. and 0.6 m. If the empty space is completely filled by a medium of dielectric constant 6, then the capacity of the capacitor will be :–

Dielectric Filled Capacitors

The capacity of a parallel plate capacitor with no dielectric substance but with a separation is reduced to half and it is filled with a dielectirc substance of value 2.8 . The final capacity of the capacitor is

In a parallel plate capacitor with air, the distance between the plates is reduced to half and the space is filled with dielectric of constant 4. If initial capacity of capacitor is 2muF , then final value of capacity is

The space between the plates orf a parallel plate capacitor is completely filled with a meterail of resistaivity 2xx10^(11) Omegam and dielectric constant 6. Capacity of the capacitor with the given dielectric medium between the paltes is 20uF. Find the leakage current if a potential difference 2500 V is applied across the capacitor.
