Question

Correct formula for capacitance in terms of area A and distance d, of a parallel plate capacitor in vacuum is



​

Answer 1

Answer:

Capacitance

Explanation:

C = E0 A / d

in vaccum or air Relative permittivity is 0 . ( Er = 0 )

E0 = absolute permittivity

Answer 2

The value of capacitance C=AE0Er/d

Explanation:

Here  C is capacitance A is area of cross-section,E0 is permetivity and Er is the relative permetivity of the medium so  here Er =1 in case of air so the formual becomes c=AE0/d

if it was glass or wood it would be AE0Er/d replace Er with 3.48 and 5.46 respectively.
