Identical dielectric slabs are inserted ...

Identical dielectric slabs are inserted into two identical capacitors `A` and `B`. These capacitors and a battery are connected as shown in figure. Now the slab of capacitor `B` is pulled out with battery remaining connected

A

During the process, charge flows from b to a

B

During the process, internal energy of the battery increases

C

Finally charge on capacitor B will be less than that on capacitor A

D

During the process, work is done by the external force F, which fully appears as heat in the circuit

Three capacitors A , B and C are connected to a battery of 25volt as shown in the figure. The ratio of charges on capacitors A

When a capacitor is connected to a battery:

Four capacitors and two batteries are connected as shown in the figure. The potential difference between the points a and b is:

The answer to each of the following questions is a single-digit integer ranging from 0 to 9. Darken the correct digit. Two identical air capacitors of capacitance C are connected to a battery of EMF V and initially switch is closed for a long time. After the switch is opened, identical dielectric slabs are inserted in between the plates of both the capacitors and it is found that energy stored in capacitor B becomes nine times of the energy stored in capacitor A. What is the dielectric constant of the slab?

A dielectric slab is inserted between the plates of a capacitor. The charge on the capacitor is Q and the magnitude of the induced charge on each surface of the dielectric is Q' .

An air core parallel plate capacitor has capacitance C. It is completely filled with a dielectric slab having dielectric constant 2 K. The capacitor is now connected to a battery of emf V. It was planned to replace the dielectric slab of the capacitor while it remains connected to the battery. Another dielectric slab (which fits exactly between the plates) is inserted slowly so as to push out the earlier slab. The new slab has a dielectric constant K [see Figure (a) to (c)] (a) By energy considerations calculate the mechanical work that must be done against the electric forces in order to complete the process. (b) Looking at the expression of mechanical work obtained in (a), tell what was the direction of force applied by the external agent - from left to right (as indicated by F_(1) in Figure) or from right to left (as indicated by F_(2) ). (c) Which dielectric slab experienced higher force of attraction from the capacitor plates during the process ?

Two capacitors A and B are connected in series with a battery as shown in the figure. When the switch S is closed and the two capacitors get charged fully, then

In the adjoining diagram all the capacitors are initially uncharged, they are connected with a battery as a shown in figure. Then
