For making a capacitor, the dielectric should have __________(a) High

1.	For making a capacitor, the dielectric should have __________(a) High relative permittivity(b) Low relative permittivity(c) Relative permittivity = 1(d) Relative permittivity neither too high nor too lowI got this question at a job interview.My question comes from Advanced Problems on Network Theory in section Network Theory and Complex Circuit Diagram of Network Theory
Answer» The correct answer is (a) High RELATIVE permittivity The explanation: Relative permittivity is for ideal dielectric which is AIR. ACHIEVING such a precise dielectric is very difficult. Low relative permittivity will lead to low VALUE of capacitance. High relative permittivity will lead to a HIGHER value of capacitance.
