Capacitance
A device consisting of two electrical conductors that are separated by a distance and used to store electrical charges is called a capacitor. The space …
A spherical capacitor consists of two concentric conducting spherical shells of radii R1 (inner shell) and R2 (outer shell). The shells …
Multiple capacitors connected serve as electrical components in various applications. These multiple capacitors behave as a single equivalent capacitor, …
Multiple capacitors can be connected in a circuit in series or parallel configuration. When the capacitor combination is connected to a battery, the …
When an archer pulls the string in a bow, he saves the work done in the form of elastic potential energy. When he releases the string, the potential …
In 1749, Benjamin Franklin coined the word battery for a series of capacitors connected to store energy. Capacitors store electric potential energy that …
Parallel plate capacitors consist of two conducting plates separated by a certain distance. However, it is mechanically difficult to hold the large plates …
The presence of a dielectric medium in a capacitor not only changes the voltage and capacitance but also affects the electric field. In general, …
Consider a polar dielectric placed in an external field. In such a dielectric, opposite charges on adjacent dipoles neutralize each other, such that the …
A neutral atom consists of a positively charged nucleus surrounded by a negatively charged electron cloud. When placed in an external electric field, the …
When placed in an external electric field, a dielectric material gets polarized. The charge density in the dielectric material is given by the sum of the …
When an electric field passes from one homogeneous medium to another, crossing the boundary between the two mediums imparts a discontinuity in the …
This contribution demonstrates the fabrication process of dielectric elastomer transducers (DETs). DETs are stretchable capacitors consisting of an …
In this work, an easy, low-cost, and widely applicable method was developed to improve the compatibility between the ceramic fillers and the polymer …
There are tremendous efforts in various fields to apply the inkjet printing method for the fabrication of wearable devices, displays, and energy storage …
