Very interesting. I guess its the same as with water, you need more pressure to maintain the same flow rate if you ad more hose length. Am I correct in thinking this is a result of I=E/R, where the R is increasing with each filament so you have to increase E to maintain I?

You've got it.
If you think in terms of watts, one tube...2.5 volts and 2.5 amps is 6.25 watts
Two tube in parallel....2.5 volts and 5 amps is 12.5 watts total, 6.25 per tube.
Two tube in series......5 volts (2.5 volt for each tube) 2.5 amps is 12.5 watts total, 6.25 watts per tube.
6 tubes in series.....15 volts (2.5 volts for each tube) 2.5 amps is 37.5 watts, 6.25 watts per tube.
