**Maxwell’s first equation or Gauss’s law in electrostatics**

**Statement.** It states that the total electric flux φ_{E} passing through a closed hypothetical surface is equal to 1/ε_{0} times the net charge enclosed by the surface:

Φ_{E}=∫E.dS=q/ε_{0}

∫D.dS=q

where D=ε_{0}E= Displacement vector Continue reading “Maxwells first and second equations and their derivation”
