What is electric dipole?

An electric dipole is an object (or, in general, a charge distribution), where the two charges are not evenly distributed . Imagine a convenient object for starts, like a rod. The positive and negative charges could be completely separated spatially, or they could be mixed but unevenly. Question: I am confused about the concept of […]

Scalar or Vector: The Nature of Electric Potential

It is easier to work with sums of scalar fields than vector fields, which makes the potential useful. Suppose we have a system of three particles with electric charges $+Q_A$, $-Q_B$, and $+Q_C$, located at positions $A$, $B$, and $C$, respectively, with position vectors $bf{r}_A$, $bf{r}_B$, and $bf{r}_C$ relative to an arbitrary origin O. The […]

Arrangement of Capacitors in Series and Parallel for Charge Distribution: A Rephrased Perspective

In reference to Fig 3, plate A becomes positively charged as the battery’s positive terminal draws electrons from it. Subsequently, plate C, which is also positively charged, will then attract and pull free electrons from plate E to plate D. As a result, plate D becomes negatively charged and plate E becomes positively charged by […]
