Question 1

A parallel plate capacitor having plate area 20 cm² and separation between the plates 1.00 mm is connected to a battery of 12.0V. The plates are pulled apart to increase the separation to 2.0 mm.

Calculate the charge flown through the circuit during the process.

Question 2

Calculate the stored energy in the electric field after the process.

Question 3

Two capacitors of capacity

and

are charged to 100volt and 50volt respectively, then arranged with the battery of emf 200volt and switches

and

as shown in the figure. Initially the switches were open. Now the switches closed.

Answer the following questions.

Magnitude of charge flown through the switches and respectively

Question 4

Work done through the battery

Question 5

To establish an instantaneous current of 2 A through a 1 microfarad capacitor the potential difference across the capacitor plates should be changed at the rate of :

Question 6

A point charge of magnitude

is fixed at (0, 0, 0)m. An isolated uncharged spherical conductor is fixed with its center at (4, 0, 0)m. The potential and the induced electric field at the centre of the sphere is :

Question 7

A parallel plate capacitor of area

and separation 3 mm is charged initially to

If the medium between the plate gets slightly conducting and the plate loses the charge initially at the rate of

then what is the magnetic field between the plates?

Question 8

A series combination of n₁ capacitors, each of capacity C₁ is charged by source of potential difference 4V. When another parallel combination of n₂ capacitors each of capacity C₂ is charged by a source of potential difference V, it has the same total energy stored in it as the first combination has. The value of C₂ in terms of C₁ is then
