Electric Potential
When an electric field accelerates a free positive charge q, it is given kinetic energy. The process is analogous to an object accelerated by a…
When an electric field accelerates a free positive charge, it acquires kinetic energy. This process is analogous to an object being accelerated by a…
Suppose a positive test charge moves away from a positive static charge, then the Coulomb force does positive work, and its electric potential energy…
For a system of charges, it is easy to calculate the system's potential because potential is a scalar quantity. However, in some instances where…
An electric dipole is a system of two equal but opposite charges, separated by a fixed distance. This system is used to model many real-world…
Electric potential can be pictorially represented as a three-dimensional surface. On such a surface, the electric potential is constant everywhere.…
The electric field and electric potential are related to each other. If the electric field at various points in the region of interest is known, it…
The electric potential of the system can be calculated by relating it to the electric charge densities that give rise to the electric potential. The…
The work done to bring a charge through a distance r is given by the potential difference between the initial and the final position. To assemble a…
Consider an external electric field propagating through a homogeneous medium. When the electric field crosses the surface boundary of the medium, it…
To drive electrohydrodynamic (EHD) flows in aqueous solutions, the separation of cation and anion transport pathways is essential because a directed…
Metamaterials (MM), artificial materials engineered to have properties that may not be found in nature, have been widely explored since the first…
