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…
A spherical capacitor consists of two concentric conducting spherical shells of radii R1 (inner shell) and R2 (outer shell). The shells…
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…
Parallel plate capacitors consist of two conducting plates separated by a certain distance. However, it is mechanically difficult to hold the large…
The presence of a dielectric medium in a capacitor not only changes the voltage and capacitance but also affects the electric field. In general,…
A neutral atom consists of a positively charged nucleus surrounded by a negatively charged electron cloud. When placed in an external electric field,…
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…
There are tremendous efforts in various fields to apply the inkjet printing method for the fabrication of wearable devices, displays, and energy…
