    \documentclass{article}
    \usepackage{amsmath}

    \begin{document}

    \begin{equation}
    w_{n} = \frac{1}{N_{d}} \sqrt{\frac{2\epsilon_{s}V_{bi}}{q(\frac{1}{N_{a}} + \frac{1}{N_{d}})}
    \end{equation}

    \end{document}

Can anyone help me spot where I'm getting an error here? Been going through this for ages trying to understand why it won't compile properly in Overleaf. It just returns a blank space in my document.

  • Maybe a closing bracket too many at the end? Just by looking at it, I did not test it. – Dr. Manuel Kuehner Nov 26 '21 at 17:40
  • @Dr.ManuelKuehner I have tried changing that and checking that several times! Possibly though, however I've tried changing this a few times now with no resolution... – user10793176 Nov 26 '21 at 17:44
  • I think you are lacking a } at the end. \documentclass{article} \begin{document} \begin{equation} w_{n} = \frac{1}{N_{d}} \sqrt{\frac{2\epsilon_{s}V_{bi}}{q(\frac{1}{N_{a}} + \frac{1}{N_{d}})}} \end{equation} \end{document} works. –  Nov 26 '21 at 17:44

    it runs without error if you add the missing } – David Carlisle Nov 26 '21 at 17:45
  • Please add a minimal working example so people can help faster. You are missing } at the end. Also, use modern IDE to help you avoid these mistakes by using automatic completion tools. – CroCo Nov 26 '21 at 17:47
  • @CroCo Excuse my basic understanding, but what is Modern IDE? I'm using Overleaf for a University project and don't really have much prior knowledge of it. – user10793176 Nov 26 '21 at 18:03
