if you have a data such as x and y
suppose x = current and y=volts
through excell you graph it
then if you want accurecy in curve you do Logarithimic scale
and you check power or for more accracy you do trendline. then you will find
equation. i have done this many times but for last 4 years i did not do that
and i forgot have to get that equation. would pleae give me a hint. thank you

Graph the X & Y, click on the line in the graph and add a trend line.
