A capacitor $P$ with capacitance $10\times 10^{-6}\mathrm{F}$ is fully charged with a potential difference of 6.0 V and disconnected from the battery. The charged capacitor $P$ is connected across another capacitor $Q$ with capacitance $20\times 10^{-6}\mathrm{F}$. The char …

The space between the plates of a parallel-plate capacitor of capacitance C (without any dielectric) is now filled with three dielectric slabs of dielectric constants ${\mathrm{K}}_1=2,{\mathrm{K}}_2=3$, and ${\mathrm{K}}_3=5$ (as shown in the figure). If new capacitance is …

A parallel plate capacitor with plate separation 5 mm is charged by a battery. On introducing a mica sheet of 2 mm and maintaining the connections of the plates with the terminals of the battery, it is found that it draws $25\%$ more charge from the battery. The dielectric con …

Three parallel plate capacitors each with area A and separation d are filled with two dielectric (k₁ and k₂) in the following fashion. Which of the following is true? (k₁ > k₂)

Identify the correct statements :
A. Effective capacitance of a series combination of capacitors is always smaller than the smallest capacitance of the capacitor in the combination.
B. When a dielectric medium is placed between the charged plates of a capacitor, displacement of c …

A parallel plate capacitor has capacitance C , when there is vacuum within the parallel plates.
A sheet having thickness ${\left(\frac{1}{3}\right)}^{\text{rd }}$ of the separation between the plates and relative permittivity K is introduced between the plates. The new capacitan …
