An uncharged capacitor with a solid dielectric is connected to a similar air capacitor charged to a potential of V0. If the common potential after sharing of charges becomes V, then the dielectric constant of the dielectric must be
- \(\frac{V_{0}}{V}\)
- \(\frac{\mathrm{V}}{\mathrm{~V}_{0}}\)
- \(\frac{\left(V_{0}-V\right)}{V}\)
- \(\frac{\left(\mathrm{V}_{0}-\mathrm{V}\right)}{\mathrm{V}_{0}}\)
Answer
(C) (V_ 0 -V ) V
