Homework Help: Max temperature for 3.2 V incandescent light bulb

  1. Jan 27, 2012 #1
    In my physics lab, I calculated a value of 5436 deg C for the max temperature of the filament by measuring its resistance. Is it possible for a filament to reach this temperature?

    I'm thinking it might be since the wire is so small that it wouldn't kill the world.

    That's far too high. Tungsten is good to not quite 4000C.

    Typical filament is around 3000C.
