What I want to know is how one should adjust the mA (mAmpere) compared to the voltage and the buffer one uses. Normally I used 1xTAE buffer (run at 90V) or 1x sodium borate buffer (run at 110V). I know that if I adjust the voltage up, the buffer heats up faster, the samples travel faster, but the "picture" of the gel becomes more blurry.

12.7: Electrophoresis
Page ID. Electrophoresis is a class of separation techniques in which we separate analytes by their ability to move through a conductive medium—usually an aqueous buffer—in response to an applied electric field. In the absence of other effects, cations migrate toward the electric field's negatively charged cathode.

Gel Electrophoresis Features Comparison
Gel electrophoresis systems utilize a porous, electrically-charged gel matrix to separate distinct nucleic acid and protein sequences based on molecular weight (or fragment size). The gel box is designed to include a cathode, or negatively-charged electrode, at one end of the medium and an anode, or positive-charged electrode, at the opposite end.
