In order to obtain a high value for capacitance, the permittivity of the dielectric medium should be?(a) Low(b) High(c) Zero(d) Unity

Answer» Right choice is (b) High

To elaborate: Form the expression:

C=epsilon*A/d.

From this expression, it is seen that capacitance is directly proportional to the permittivity, hence for capacitance value to be high, permittivity value should be high.
