Rather simple ? regarding gel electrophoresis

just out of curiosity, i've always wondered why, when i set it for
the same voltage, different power machines read different values
for the mA.  when i set the machine at 100V, for example, one machine
might read 70mA while another reads 90mA.  

these machines are the same brand and model, so i don't think it could
be because of different machine specifications.

also, does this discrepancy in mA affect results (resolution, etc)?
i mean, do some of these machines produce better results than others?
