B M Sharma Solutions for Chapter: Capacitor and Capacitance, Exercise 6: Exercise

Three capacitors $A,B$, and $C$ are connected in a circuit as shown in figure. What is the charge in $\mathrm{\mu C}$ on the capacitor $B$?

Three capacitors are connected as shown in the figure. Then, the charge on capacitor $C_1$ is

A capacitor of capacitance $C_1=1 \mathrm{\mu F}$ charged up to a voltage $V=110 \mathrm{V}$ is connected in parallel to the terminals of a circuit consisting of two uncharged capacitors connected in series and possessing capacitances $C_2=2 \mathrm{\mu F}$ and $C_3=3 \mathrm{\mu F}$. Then, the amount of charge that will flow through the connecting wires is:

In figure, three capacitors $C_1,C_2$, and $C_3$ are joined to a battery. With symbols having their usual meaning, the correct conditions will be

An uncharged parallel plate capacitor having a dielectric of dielectric constant $K$ is connected to a similar air-cored parallel plate capacitor charged to a potential $V_0$. The two share the charge, and the common potential becomes $V$. The dielectric constant $K$ is

Two identical parallel plate capacitors are connected in series and then joined in series with a battery of $100 \mathrm{V}$. A slab of dielectric constant $K=3$ is inserted between the plates of the first capacitor. Then, the potential difference across the capacitors will be, respectively,

Two plates of a parallel plate capacitor carry charges $q$ and $-q$ and are separated by a distance $x$ from each other. The capacitor is connected to a constant voltage source $V_0$. The distance between the plates is changed to $x+dx$. Then in steady-state

Three identical parallel conducting plates $A, B$ and $C$ are placed as shown. Switches $S_1$ and $S_2$ are open, and can connect $A$ and $C$ to earth when closed. $+Q$ charge is given to $B$.
