Gauss's Law: The mathematical relationship between the electric field coming from the electric flux and the enclosed charge.
Parallel Plate Capacitance: The capacitance between two parallel plates separated by a distance "d" having surface area "A" is known as parallel plate capacitance.
Spherical Capacitance: When two charged metallic spheres, having radii R1 and R2, are placed at a specific distance 'd' apart, the capacitance so produced is known as the spherical capacitance.
Cylindrical Capacitance: When a charged or uncharged conductor is placed between two concentric cylinders at a particular distance, this produces cylindrical capacitance.
Concentric Capacitance: When two concentric cylinders with radii a and b having surface charge densities of +σ and -σ (opposite to each other), are separated by a distance "d," the capacitance produced is known as concentric capacitance.
Stray Capacitance: When any two conductors are present close to each other but not physically connected, this capacity is known as stray capacitance.
Dielectric Capacitance: When a dielectric material is placed between two parallel plates, it may increase or decrease the capacitance of the plates based on the dielectric constant of the medium.
Fringing Capacitance: The capacitance that arises due to the electric field extending into regions outside the plates is known as fringing capacitance. It plays a significant role in micro-optics and microelectronics.
Mutual Capacitance: The capacitance between two sets of conductors sharing the same electric field is referred to as mutual capacitance. It's used for precision measurements in various applications like smart electronic devices, biosensors, and robots.
Self Capacitance: The capacitance that develops in a conductor when it carries an electrical charge is termed self-capacitance. It is used in various applications like touch sensing, display technologies, and more.
Interwinding Capacitance: This is the capacitance that develops due to the coupling between two or more coils or windings. It is observed in the design of power transformers, electrical generators, and more.
"Capacitance is the capability of a material object or device to store electric charge."
"It is measured by the charge in response to a difference in electric potential, expressed as the ratio of those quantities."
"Commonly recognized are two closely related notions of capacitance: self capacitance and mutual capacitance."
"An object that can be electrically charged exhibits self capacitance, for which the electric potential is measured between the object and ground."
"Mutual capacitance is measured between two components, and is particularly important in the operation of the capacitor."
"The capacitance between two conductors is a function only of the geometry; the opposing surface area of the conductors and the distance between them, and the permittivity of any dielectric material between them."
"For many dielectric materials, the permittivity, and thus the capacitance, is independent of the potential difference between the conductors and the total charge on them."
"The SI unit of capacitance is the farad (symbol: F)."
"The farad is named after the English physicist Michael Faraday."
"A 1 farad capacitor, when charged with 1 coulomb of electrical charge, has a potential difference of 1 volt between its plates."
"The reciprocal of capacitance is called elastance."
