COMBINATION OF CAPACITORS

A potential of V = 3000 V is applied to a combination of four initially uncharged capacitors as shown in the figure. Capacitors A, B, C and D have capacitances C_(A)=6.0 muF,C_(B)=5.2 muF,C_(C)=1.5 muF and C_(D) = 3.8 muF , respectiely. If the battery is disconnected, then potential difference across capacitor B is (approximately)

A combination arrangement of the capacitors is shown in the figure (i) C_(1)=3 mu F, C_(2) =6 mu F and C_(3)= 2 mu F then equivalent capacitance between 'a' and 'b' is :

An a.c. voltage of (V = 100 sin omega t) volt is connected across the parallel combination of inductor and capacitor having ( X_L = 5 Omega) and (X_C = 10 Omega) then current supplied by source is (in ampere)

A series combination of resistor (R), capacitor (C) is connected to an AC source of angular frequency omega . Keeping the voltage same, If the frequency is changed to Omega/3 , the current becomes half of the original current. Then, the ratio of the capacitance reactance and resistance at the former frequency is

Combinations and Comparison of Capacitors and Resistors

If the equivalent capacitance between points P and Q of the combination of the capacitors show in figure below us 30 muF , the capacitor C is

The equivalent capacitance of the combination of three capacitors each of capacitance C between A and B as shown in figure is

Effective capacitance of parallel combination of two capacitors C_(1) and C_(2) is 10muF . When the capacitors are individually connected to a voltage source of 1V, the energy stored in the capacitor C_(2) is 4 times of C_(1) . If these capacitors are connected in series, their effective capacitor will be: lt

A capacitor of 10 muF and an inductor of 1 H are joined in series. An ac of 50 Hz is applied to this combination. What is the impedance of the combination?
