How to increase capacitance?
|
|
A capacitor’s plates should be positioned closer together
|
|
|
A capacitor’s plates should have more surface area.
|
|
|
Adding a dielectric as an insulator between the two plates
|
|
|
A capacitor’s plates should have less surface area.
|
Explanation:
Detailed explanation-1: -The larger the dielectric constant, the more charge can be stored. Completely filling the space between capacitor plates with a dielectric increases the capacitance by a factor of the dielectric constant: C = KCo, where Co is the capacitance with no dielectric between the plates.
Detailed explanation-2: -If you want to increase the Capacitance of Parallele Plate Capacitor then increase the surface area, reduce the separation between the plate and use a dielectric material in between the plate which have higher dielectric breakdown strength.
Detailed explanation-3: -The dielectric is an insulating material which decreases the electric field between the plates and hence, it will increase the capacitance.
