AlonsoDT Posted October 1, 2010 Report Share Posted October 1, 2010 Hello fellow ibers! I have a problem with one of my physics lab on circuits. I'm trying to find the relationship between an ohmic resistance and a non ohmic resistance in a series circuit. When I make the graph relating these two variables, I find out that the absolute uncertainties are too small and the error bars don't show... I was wondering if I could just omit this in the graph (justifying later why I did so), would that take me a lot of point from DCP? Thanks!

Sublime Sunshine Posted October 1, 2010 Report Share Posted October 1, 2010 Dont worry, If the uncertainties in some measurements are negligible then you can omit error bars. You can provide justification for this, but as long as you show the calculation of uncertainties then that should fulfil DCP 1 Reply Link to post Share on other sites More sharing options...
AlonsoDT Posted October 1, 2010 Author Report Share Posted October 1, 2010 Ok, thanks a lot SS! That's exactly what I've done Reply Link to post Share on other sites More sharing options...
dessskris Posted October 1, 2010 Report Share Posted October 1, 2010 I think that you still need to show I think if you don't show the error bars, they will give you 'partial'. if you put it, then you can conclude that the error is way too small that the extreme lines seem very close to the best fit line. then say that it means your results are very accurate. or do something like that. that's what I think.

Tilia Posted October 1, 2010 Report Share Posted October 1, 2010 I've had the same problem and were told to include them, but say that "the error bars are so small that they don't show". Reply Link to post Share on other sites More sharing options...
