If You Increase The Distance Between The Plates Of A Capacitor, How Does The Capacitance Change?
Factors Affecting Capacitance
A capacitor is an electrical device designed for storing electrical charge, by and large consisting of two parallel conducting plates separated past an insulating layer called a dielectric.
Click on the arrows to select diverse combinations of dielectrics, plate areas, and distances.
The capacitance of a capacitor is affected by the area of the plates, the distance betwixt the plates, and the ability of the dielectric to support electrostatic forces. This tutorial explores how varying these parameters affects the capacitance of a capacitor. Larger plates provide greater capacity to shop electrical charge. Therefore, every bit the area of the plates increase, capacitance increases.
Capacitance is directly proportional to the electrostatic strength field betwixt the plates. This field is stronger when the plates are closer together. Therefore, as the altitude betwixt the plates decreases, capacitance increases.
Dielectric materials are rated based upon their ability to back up electrostatic forces in terms of a number called a dielectric constant. The college the dielectric constant the greater the ability of the dielectric to support electrostatic forces. Therefore, every bit the dielectric abiding increases, capacitance increases.
