Lights on the Titanic

These seems totally impossible to me. There was a brief seen in the movie that showed a chandeleer still lit when the room was completely submerged in water. I thought, how can that luxurious fancy chandeller not short out when under water? In real life how long will that thing have before it shorts? Here is a picture of the lounge (see attached).

    I guess the FX editors were probably hoping no one would be observant enough to think about that.

    That ship had four 400kW dynamos. The voltage they produced was 100 volts.

    Some offerings from Hollywood require more "suspension of disbelief" than others --·and Titanic·required it·on many levels.

    Yes, those of us associated with that business·refer to those things as "artistic license" tongue.gif··

    I can empathize, though, as being a technically-inclined guy I am more frequently pulled from my suspension of disbelief than most casual audience members.·

    Bruce Willis in 'Last Man Standing' had magical guns that would fire 50bullets from a 20clip....I thought that was awesome!! haha Kinda like taking away the blue line in hockey....MORE ACTION!

    As the ship went down, Id think the fuse on the local distrubution panel would blow as soon as water made contact with the light bulb sockets. Yet I am still puzzled because I sucessfully submerged a non-water resistent battery powered light in water and it did not short.

    I do despise disbelief and preach pure realism. Most people would find that boring, however it is in truth more interesting.

    I know for a fact that cars when submerged underwater (fresh) can have thier electronic accessories operate for upto 1/2 hour. In salt water it is much shorter, but this is mainly due to the salt water surrounding the battery acts as a short, inhibiting it's ability to deliver current through the wires (similar as if you placed a low value resistor across your BOE-bot battery when it's operating). In a situation such as the titanic several factors will be involved, such as is the room containing the dynamos submerged, how well the wires are insulated between the dynamos and the chandelier and how well the bulbs are screwed into thier socket. If I remember correctly the survivors reported that the lights remained on while the ship sank (I don't remember if they were still on when it completely submerged), so that leads one to believe that the dynamos were still working. Whether a light fixture in a particular room was lit when it was completely filled will never be known because anyone there to observe it died.

    Im not sure if the conductivity of saltwater would have been sufficient to trip the fuses, light fixtures typically have pretty low resistance themselves. Saltwater has a conductivity of 4 Siemen/meter or 0.25 Ohms/meter, not knowing what the fuses were rated for and how many lights were on each circuit its impossible to figure whether the fuses would have blown.

    I, for one, am looking forward to the day you start preaching, "Read the manual or help file -- it's an easy read and worth the time."...
