$\begingroup$ Well, actually if there was no resistance, even for a constant voltage the current will be constantly increasing, but electrons will constantly accelerate due to external elect field (voltage) applied (at least if to talk about generator as the source) $\endgroup$

$\begingroup$ In real conductor, electrons are still constantly accelerated by voltage, but every time, some part of the incoming kinetic energy will be lose due to bumping in obstacles, i.e. on heating (that is described by Joule-Lentz law) $\endgroup$

$\begingroup$ If to consider a single electron, obviously, the distance that it can move freely before bumping in something is tiny, but there are more than one electron, and if to consider the whole picture, I think my assumption will make sense $\endgroup$
