C_(1) = 20 muF, C_(2) = 30 muF and C_(3) = 15 muF are connected in series and the insulated plate of C_(1) is at a potential of 90 V, one plate of C_(3) being earthed. What is the potential difference between the plates of C_(2) ?

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 -

Both the capacitors shown in figure are made of square plates of edge a . The separations between the plates of the capacitors and d_(1) and d_(2) as shown in the figure. A battery of V volt and a resistance R are connected as shown in figure. At steady state an electron is projected between the plates of the lower capacitor from its lower plate along the plate as shown. Minimum speed should the electron be projected is given by (1)/(sqrt(n))((Vea^(2))/(md^(2)))^(1//2) so that it does not collide with any plate? Consider only the electric forces then find the value of n.

Two parallel-plate capacitors with different distances between the plates are connected in parallel to a voltage source. A point positive charge is moved from a point A , that is exactly in the middle between the plates of a capacitor C_(1) to a point B (or a capacitor C_(2) that lies at a distance from the negative plate of C_(2) equal to half the distance between the plates of C_(1) ) During this process of moving the charge. .

The capacity of a parallel plate condenser without any dielectric is C. If the distance between the plates is doubled and the space between the plates is filled with a substance of dielectric constant 3, the capacity of the condenser becomes:

A parallel plate condenser is charged by connected it to a battery. The battery is disconnected and a glass slab is introduced between the plates. Then

One plate of a capacitor is fixed, and the other is connected to a spring as shown in. Area of both the plates is A In strady state (equilibrium), separation between the plates is 0.8d (spring was unstretched , and the distance between the plates was d when capacitor was uncharged). The force conntant of the spring is approximately.

The distance between the plates of a parallel plate capacitor is 0.04m A field of 5000V//m is established between the plates and an unchanged metal plate of thickness 0.01m is inserted intothe condenser parallel to its plate. Find the p.d . between the plates (a) before the introducing of the metal plate and (b) after its introduction. what would be the p.d. if plate of dielectric constant K=2 is introduced in place of metal plate?

Assertion. Capacity of a parallel plate condenser remains unaffected on introduced a conducting or insulating slab between the plates. Reason. In both the cases, electric field intensity between the plates increases.

Two identical capacitor C_(1) and C_(2) are connected in series with a battery. They are fully charged. Now a dielectric slab is inserted between the plates of C_(2) . The potential across C_(1) will :
