Firewire specs on TiBook screwy?

I have been reading over the Developer Notes on the new Powerbook G4, and am confused about this minor detail... <a href="http://developer.apple.com/techpubs/hardware/Developer_Notes/Macintosh_CPUs-G4/PowerBook_G4/1Introduction/Features.html"; target="_blank">This Page</a>

Says the battery puts out a maximum of 14.4 volts. I was then reading about the firewire specs on <a href="http://developer.apple.com/techpubs/hardware/Developer_Notes/Macintosh_CPUs-G4/PowerBook_G4/3Input-Output/FireWire_Connector.html"; target="_blank">This Page</a> and it says the Firewire port puts out 17 volts.. But how is this possible on a 14.4 volt battery? I thought the only way to increase DC voltage was to use an ac invertor and a transformer... I know this is a minor detail, but I would sure like to know how it works. Thanks.

Sorry for bumping this, but I really want to figure this out. I will not bump it again. Just letting you know I have not figured it out yet.

Ever hear of Ohms Law? Volts = Amps times Resistance. Check out this link: <a href="http://webhome.idirect.com/~jadams/electronics/ohm.htm"; target="_blank">http://webhome.idirect.com/~jadams/electronics/ohm.htm</a>;



I don't know if this applies to the TiBook, but it's something to think about.
