How can capacitance be increased?

Answer 1

Nora Arzate

By introducing a dielectric slab in between the plates.

Capacitance of a parellel plate capacitor is given by

#"C" = (ε_0"A")/"d"#

On introduction of a dielectric slab of dielectric constant #K# in an isolated charged capacitor

#"C’" = (Kepsilon_0"A")/"d"#

#"C’" = K"C"#

Capacitance becomes #K# times of original capacitor.

Capacitance can be increased by:

Increasing the surface area of the capacitor plates.
Decreasing the distance between the capacitor plates.
Using materials with higher permittivity between the plates.
Adding dielectric materials between the plates.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
