If the air-core medium is replaced by a dielectric of dielectric constant \(k\) in an air-core parallel plate capacitor of capacitance \(C\), its new capacitance becomes
Show Hint
When a dielectric fully fills the space between capacitor plates:
\[
C' = kC
\]
Capacitance always increases.

The Correct Option is
Solution and Explanation
Capacitance of a parallel plate capacitor becomes \(k\) times when a dielectric medium of dielectric constant \(k\) is inserted.
So if original capacitance is:
\[
C
\]
New capacitance becomes:
\[
C' = kC
\]
Hence, the correct answer is the option corresponding to: \[ \boxed{kC} \]
Hence, the correct answer is the option corresponding to: \[ \boxed{kC} \]
