Co is the capacitance of a parallel plate capacitor with air as a medium between the plates (as shown in Fig. 1). If half space between the plates is filled with a dielectric of relative permittivity $\varepsilon $r (as shown in Fig. 2), the new capacitance of the capacitor will be :

Question

C_o is the capacitance of a parallel plate capacitor with air as a medium between the plates (as shown in Fig. 1). If half space between the plates is filled with a dielectric of relative permittivity $\varepsilon $_r (as shown in Fig. 2), the new capacitance of the capacitor will be :

${{{C_o}} \over 2}(1 + {\varepsilon _r})$

${C_o} + {\varepsilon _r}$

${{{C_o}{\varepsilon _r}} \over 2}$

${C_o}(1 + {\varepsilon _r})$
