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 $A/V^n$.
