Equation numbering in Appendix. iopart document class

Question

I want the mathematical equations in my Appendices to be numbered as A.1, B.1, C.1.. etc.

However, it is showing as 1.1, 2.1, 3.1.. and so on. How can I remove this error? I am already using packages-

\usepackage[title,titletoc,toc]{appendix}
\usepackage{titlesec}

in \documentclass[oneside,preprint,12pt,3p]{iopart}.

Do not use \numparts, always use \begin{subequations}. That was the issue. Now solved. :)

Thanks for the answer. Can you explain what's the problem with \numparts? – Dr. Manuel Kuehner Jun 22 '20 at 10:13

The format for equation numbering in Appendix should be- A.1, A.2... etc. Using \numparts converts the numbering to 1.1, 1.2 etc. So depending upon which format you want, you can choose between \numparts or \begin{subequations} – Rupal Srivastava Jun 29 '20 at 17:41
