Capacitor PYQs - Last 10 Years

A dielectric slab of dielectric constant $k=3$ is filling $\frac{3}{4}$ th space of the capacitor.

When capacitor is charged, then \% of total energy stored in dielectric is

A parallel plate capacitor consists of two circular plates of radius $ R=0.1 \mathrm{~m} $. They are separated by a short distance. If electric field between the capacitor plates changes as $ \frac{d E}{d t}=6 \times 10^{13} \frac{\mathrm{~...

The separation between two parallel plates of capacitor is 1 mm. What is the electric potential generates between the plates of capacitor, when electric field of 2000 N/C is applied on it?

Three capacitors C1, C2 and C3 are connected as shown in the figure below. If capacitor C3 breaks down electrically, the change in total charge on the combination of capacitors is
