MCQ (Single Correct Answer)

-1

A series combination of n₁ capacitors, each of value C₁, is charged by a source of potential difference 4V. When another parallel combination of n₂ capacitors, each of value C₂, is charged by a source of potential difference V, it has the same (total) energy stored in it. as the first combination has. The value of C₂. in terms of C₁, is then

$${{2{C_1}} \over {{n_1}{n_2}}}$$

$$16{{{n_2}} \over {{n_1}}}{C_1}$$

$$2{{{n_2}} \over {{n_1}}}{C_1}$$

$${{16{C_1}} \over {{n_1}{n_2}}}$$
