Good write up. Thank you for explaining in details what a JFET is and it's working principle. But did you produce the images yourself? Cos I think the credit is not well stated.
However, there some areas you might need help in improving. If you already are part of the steemstem community on discord, Pls request for a mentor. And if not let me know so I can give you the link to join.
