I=kV^n filament lamp hnc assignment

  1. Jan 7, 2008 #1
    1. The problem statement, all variables and given/known data
    what does k and n relate to? i can work them out but dont know exactly what they are.


    2. Relevant equations
    I=kV^n


    3. The attempt at a solution
    i think the k and n have something to do with temperature and the tungsten metal in the lamp (coefficient of resistance?)? if any one can help that would be much appreciated.

    The n is just a dimensionless number, and the k is a coefficient with units of [itex]A/V^n[/itex].
