I have a graph of B against I (mag.field v current) with error bars for uncertainties in both (although i'm not sure error bars are necessary). If I plot a regression line and get a formula of the form B = mI + C, how do I get the uncertainty in B for a value of I? Is it acceptable to take the standard errors for m and c (given by excel) and use these as [tex]\Delta[/tex]m and [tex]\Delta[/tex]c along with [tex]\Delta[/tex]I in the error combination rules (http://level1.physics.dur.ac.uk/skills/randomerrors.php)?
