    If  a capacitor’s dielectric constant is vacuum its dielectric constant is k will be equal to 1.

    Explanation:

    Relative permittivity of  a dielectric substance is referred to as its dielectric constant. Relative permittivity/dielectric constant k is a dimensionless quantity that is the ratio of absolute permittivity and vacuum permittivity.

    It is given by the expression

    k=k=ε /ε0

    where ε denotes absolute permittivity and  ε0 denotes permittivity of vacuuum.

    Absolute permittivity  ε of vacuum= ε0

    therefore k= ε0/ ε0=1

    dielectric constant of vacuum is 1 .
