Embibe Experts Solutions for Chapter: Capacitance, Exercise 1: Exercise - 1

The charge on each of the capacitors $0.16 \mathrm{m} \mathrm{s}$ after the switch $S$ is closed in figure is:

The switch $S$ shown in figure is kept closed for a long time and then opened at $t=0,$ then the current in the middle $20 \mathrm{\Omega }$ resistor at $t=0.25 \mathrm{ms}$ is

The effective capacitance of the system in adjoining figure will be,

In the adjoining diagram, two geometrically identical capacitors $A$ and $B$ are connected to a battery. Air is filled between the plates of $C_1$ and a dielectric is filled between the plates of $C_2,$ then

A parallel plate condenser is connected to a battery of emf $4 \mathrm{volt}.$ If a plate of dielectric constant $8$ is inserted into it, then the potential difference on the condenser will be 

A parallel plate condenser is connected to a battery of EMF $4 \mathrm{volt}.$ If a plate of dielectric constant $8$ is inserted into it if the battery is disconnected before inserting the dielectric, then the potential difference will be, 

A parallel plate condenser with plate separation $d$ is charged with the help of a battery so that $U_0$ energy is stored in the system. A plate of dielectric constant $K$ and thickness $d$ is placed between the plates of condenser while battery remains connected. The new energy of the system will be, 

A parallel plate condenser with plate separation $d$ is charged with the help of a battery, so that $U_0$ energy is stored in the system. A plate of dielectric constant $K$ and thickness $d$ is placed between the plates of the condenser, the battery is disconnected before placing the plate, then new energy will be
