First, we have to find out what the term electrostatic actually means, so here are again our Maxwell's
equations from the previous section.
So there were four of these equations and two of them were related to the electric field and the other
two were related to the magnetic field.
And so, as you may expect already, by the term electrostatic, we are here only concerned with the
electric fields.
And furthermore, since the term includes static's, it means that our fields E and B, our time independent.
So this means that this term here, the partial derivative of the magnetic field with respect to time
is equal to zero.
So this means here we only consider with these two equations here that the divergence of the electric
field is basically given by the charged density, which which is position dependent.
So it could be zero of our.
And the other equation would be that the rotation of E is zero.
And then, of course, according to these differential formulations of these two equations, we can
also express here the integral formulations.
So the first one looks as before and the second one is here, zero on the right side, because this
time derivative of the magnetic field is zero.
