Two capacitors of 3 µF and 6 µF are connected in series with a battery of P.d. 12 V. The P.d. across 3µF and 6µFcapacitors respectively will be : 8 V, 4 V 8 V 4 V 8 V, 47 V 2 / 10 Q.52 An electric charge of 425 f µC is removed from a fully charged capacitor of capacitance 8.5µF. Its potential will be lowered by: 100V 200V 10V 20V 3 / 10 53. A dielectric is placed in between the two parallel plates of a capacitor as shown in the figure. The dielectric constant of the dielectric being K. If the initial capacity is C, then the new capacity will be: (K + l).C K.C (K+1)2 C (k – l) C 4 / 10 54. Minimum number of capacitor of 2µF each required to obtain a capacitance of 5µF will be: 4 2 3 6 5 / 10 55. When a dielectric slab is introduced between the plates of a parallel plate capacitor which remains connected to a battery then charge on the plates relative to earlier charge is : more less less or may be more same 6 / 10 56.
