Problem

A series combination of

n_1

capacitors, each of value

C_1

, is charged by a source of potential difference 4 V. When another parallel combination of

n_2

capacitors, each of value

C_2

, 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

C_2

, in terms of

C_1

, is then: (2010 Pre) (a)

\frac{16C_1}{n_1 n_2}

(b)

\frac{2C_1}{n_1 n_2}

(c)

16 \frac{n_2}{n_1} C_1

(d)

2 \frac{n_2}{n_1} C_1
