A parallel plate air-core capacitro is connected across a source of constant potential difference. When a dielectirc plate is introudced between the two plates then:

A parallel plate capacitor is connected across a source of covstant potential difference. If a dielectric slab is introduced between the two plates, then

When a parallel plate capacitor is connected to a source of constant potential difference

A parallel plate air capacitor of plate separation d is charged to a potential difference triangle V . A slab of thickness d and dielectric constant k is introduced between the plates while the battery remains connected. Find the ratio of energy stored in the capacitor after and before the introduction of the dielectric slab.

A parallel plate air capacitor of plate separation d is charged to a potential difference triangle V . A slab of thickness d and dielectric constant k is introduced between the plates while the battery remains connected. What happens to the charge on the capacitor?

A parallel plate capacitor with air between the plates is charged to a potential difference of 500 V and then insulated. A plastic plate is inserted between the plates filling the whole gap. The potential difference between the plates now becomes 75V. The dielectric constant of plastic is
