Question

Write any two Maxwell's equation.

Answer 1

Gauss law of electrostatics: This law states that the electric flux through a closed surface S is $\frac{1}{{\in }_o}$ times
the total changes q enclosed by the surface S.
$\oint \overrightarrow{E}.\overrightarrow{ds}=\frac{q}{{\in }_o}$
(2)Modified Ampere's law : This law states that the line integral of the magnetic field around any closed circuit C is equal to go times the total current (sum of conduction & displacement currents) threading the closed circuit.
$\oint \overrightarrow{B}.\overrightarrow{d\ell }={\mu }_o[\sum I_c+\sum Id]={\mu }_o[\sum I_c+{\in }_o\frac{d\varphi }{dt}$
