Answer to Question #46723 in Physics for irebami

Question

In an experiment to determine the relationship between the current I through a piece of tungsten wire and the potential difference V across it, the theoretical relationship used was
I=kVn
, where k and n are constants which may be obtained from a straight line graph of the form y = mx + c, the symbols having their usual meaning. The corresponding linear equation for this experiment is ----------
I = nV + k
4I=nV^2+k
I=expV^n+k
logI = nlogV + logk
