Two identical parallel plate capacitor are connected in series and the combination is connected with a battery as shown. Some changes in capacitor 1 are now made independently after the steady state is achived listed in column I. Some effects which may occur in new steady state due to these changes on the capacitor 2 are listed in column II. Match the changes on capacitor 1 in column I with corresponding effect on capacitor 2 in column II.
Column-I | Column-II |
(i) A dielectric slab is inserted | [A] charge on capacitor increases |
(ii) separation between plates is increased | [B] charge on capacitor decreases |
(iii) A metal plate is inserted connecting both plate | [C] Energy stored in capacitor increases |
(iv) Separation between is plate decreased | [D] Electric field between The plates of capacitor increase |
[E] Potential difference across the plate of capacitor will increase |
