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 when the potential difference across the condenser reduces to \[{{V}_{2}}\] is

• A. \[{{\left( \frac{C(V_{1}^{2}-V_{2}^{2})}{L} \right)}^{1/2}}\]
• B. \[{{\left( \frac{C{{({{V}_{1}}-{{V}_{2}})}^{2}}}{L} \right)}^{1/2}}\]
• C. \[\frac{C(V_{1}^{2}-V_{2}^{2})}{L}\]
• D. \[\frac{C({{V}_{1}}-{{V}_{2}})}{L}\]
