A capacitor of 10 \(\mu\text{F}\) charged up to 200 V is connected in parallel with another capacitor of 20 \(\mu\text{F}\) charged up to 50 V. The common potential is:

As shown in the figure two capacitors \( C_{1} \) \& \( C_{2} \) each having same gap between the plates x filled with different media of dielectric constants 3K and 6K respectively. If these two capacitors are connected to a battery, the ratio of potential differences across dielectric layers of \( C_{1} \) and \( C_{2} \) is:

When dielectric is inserted between the plates of a capacitor with battery connected, energy increases because of:

A parallel plate capacitor with dielectric is charged completely and the battery is then disconnected. Now if the dielectric is slowly pulled out of the capacitor then the variation of the potential (V) of the capacitor with respect to the length (x) of the dielectric pulled out is represented by

Three capacitors of capacitances $3\ \mu\text{F}$, $3\ \mu\text{F}$ and $3\ \mu\text{F}$ are connected in series. The equivalent capacitance is

A capacitor has capacitance $C$. When dielectric of constant $3$ completely fills it, new capacitance is:

25 capacitors each of capacitance \(1\ \mu\text{F}\) are connected in series to a battery of \(100\ \text{V}\). The total charge stored on the capacitors is

A capacitor has capacitance \(C_0\) when there is no dielectric between its plates. Two slabs of dielectric constants \(K_1\) and \(K_2\), each having area equal to the area of the plates but thickness equal to half of the separation between the plates, are placed between the plates. Then the new capacitance is:

In a parallel plate capacitor, if \(10^{12}\) electrons pass from one plate to another, a potential difference of \(10\,\text{V}\) is developed across the plates. The capacitance of the capacitor is:
