Class 12 Physics Chapter 2 Electrostatic Potential & Capacitance Important Questions | Quick Revision | Part 2

Capacitor 3 in Fig. 25-40a is a variable capacitor (its capacitance C_3 can be varied) Figure 25-40b gives the electric potential V_1 across capacitor 1 versus C_3 The horizontal scale is set by C_3s=12.0 mu F Electric potential V_1 approaches as asymptote of 8.0 V as C_3 to infty What are (a) the electric potential V across the battery , (b) C_1 and (c) C_2 ?

In Fig. 25-7a switch S is closed to connect the uncharged capacitor of capacitance C = 0.25 mu F to the battery of potential difference V=12V. The lower capacitor plate has thickness L=0.50 cm and face area A= 2.0 times 10^-4 m^2 and it consists of copper in which the density of conduction electrons is n=8.49 times10^25 electrons/ m^3 . From what depth d within the plate (Fig.25-7b) must electrons move to the plate face as the capacitor becomes charged?

A charge of +2.0xx 10 ^-8 C is placed on the positive place and a charge of - 1.0 xx 10 ^-8 C on the negative plate of a parallel- plate capacitor of capacitance 1.2 xx (10^-3) mu F. Calculate the potential difference developed between the plates.

Find the equivalent capacitance for the combination of capacitances shown in fig.25-10a, across which potential difference V is applied . Assume (a) C_1=12.0 mu F,C_2=5.30 mu F and C_3=4.50 mu F (b) The potential difference applied to the input terminals in fig.25-10a is V=12.5V What is the charge on C_1 ?
