  A relation between classical electrostatic fields and Schr\"odinger-like
Hamiltonians is evidenced. Hence, supersymmetric quantum potentials analogous
to classical electrostatic fields can be constructed. Proposing an ansatz for
the electrostatic potential as the natural logarithm of a nodeless function, it
is demonstrated that the electrostatic fields fulfil the Bernoulli equation
associated to a second-order confluent supersymmetric transformation. By using
the so-called confluent algorithm, it is possible, given a charge density, to
find the corresponding electrostatic field as well as the supersymmetric
potentials. Furthermore, the associated charge density and the electrostatic
field profile of Schr\"odinger-like solvable potentials can be determined.
