Two condensers of capacity `C_(1)` and `C_(2)`, are connected in series to a battery as shown in Fig. The adjoining graph shows the variraton of potential in going from `a` to `b`. Thereofore.

Options

A. `C_(1) gt C_(2)`
B. `C_(1)= C_(2)`
C. `C_(1) lt C_(2)`
D. Cannot say

Answer

C

Explanation

Refer to Fig. Potential of outer plate of `C_(1)` is zero as negative of battery is earthed. As inner plate of `C_(1)` si at positive pot. The potential rises, Inner plate of `C_(2)` is at the same potential as inner plate of `C_(1)`. Therefore, potential remains constant. The graph shows that potential rises further. This indicates that `V_(2) gt V_(1)`. As `Q` is same in series combination, therefore `C_(2) gt C_(1)` or `C_(1) lt C_(2)`.
