Question

1. Ratio of capacitance of a capacitor with di electric as medium to the capacitance
of the same capacitor with air as dielectric is called______
2.The amount of charge required to create a unit potential difference across the
plates of a capacitor is called ________​

Answer 1

Ans=1

ielectric constant, also called relative permittivity or specific inductive capacity, property of an electrical insulating material (a dielectric) equal to the ratio of the capacitance of a capacitor filled with the given material to the capacitance of an identical capacitor in a vacuum without the dielectric material ...

Ans=2As capacitance represents the capacitors ability (capacity) to store an electrical charge on its plates we can define one Farad as the “capacitance of a capacitor which requires a charge of one coulomb to establish a potential difference of one volt between its plates” as firstly described by Michael Faraday.
