If a capacitor's dielectric constant is vacuum its dielectric constant is k will be equal to 1.
<u>Explanation:</u>
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 .
True is the answer. I believe
If he feels like, is interested in it, and is able to grasp it, then why not ? Why not indeed ?
Answer:
The batteries make it possible to store the electricity generated when the sun and wind peak so it can be available to the grid when electricity demand is at its peak.

Hope this helps!
If not, I am sorry.
