Constant electric field in vacuum

Node id: 1314page
  • Strength and potential of the field of a point charge $q$:$$ \vec{E}=\frac{1}{4\pi {\varepsilon}_0}\frac{q}{r^3}\vec{r},   \phi=\frac{1}{4\pi {\varepsilon}_0}\frac{q}{r}.$$
  • Relation between field strength and potential:$$\vec{E}=- \vec{\nabla}\phi. $$ i.e. field strength is equal to the anti gradient of the potential.
  • Gauss's theorem and circulation of the vector $\vec{E}$:$$\oint \vec{E}.d\vec{S}=\frac{q}{{\varepsilon}_0}, \oint  \vec{E}.d\vec{r}=0.$$

[NOTES/EM-04010] Energy of Charged Capacitor and Force Between the Plates

Node id: 5984page

The electrostatic energy stored in electric field is given by \[\mathcal E = \frac{\epsilon_0}{2}\int |\vec E|^2 d^3r.\] In this article a few selected applications of the above expression for electrostatic energy to the problems involving capacitors are discussed.

[NOTES/EM-04014] Electric Potential in Presence of Conductors

Node id: 5982page

The Maxwell's equations imply that the electric potential \(\phi\) obeys Poisson equation \(\nabla^2 \phi = -\rho/\epsilon_0,\) where \(\rho\) is the charged density.
