Given a number of capacitors labelled as `C,V`. Find the minimum number of capacitors needed to get an arrangement equivalent to `C_(net),V_(net)`.

A

`n=(C_("net"))/(C) xx(V_("net")^(2))/(V^(2))`

B

`n=(C)/(C_("net"))xx(V^(2))/(V_("net")^(2))`

C

`n=(C)/(C_("net"))xx(V)/(V_("net"))`

D

`n=(C_("net"))/(C)xx(V_("net"))/(V)`
