A condenser of capacity `C` is charged to a potential difference of `V_(1)`. The plates of the condenser are then connected to an ideal inductor of inductance `L`. The current through the inductor wehnn the potential difference across the condenser reduces to `V_(2)` is

Options

A. `((C(V_(1) - V_(2))^(2))/(L) )^(1//2)`
B. `(C(V_(1)^(2) - V_(2)^(2)))/(L) `
C. `(C(V_(1)^(2) + V_(2)^(2)))/(L)`
D. `((C(V_(1)^(2) - V_(2)^(2)))/(L) )^(1//2)`

Answer

D
