I'd like to know if you, the electronic engineers of the world wide web, find these calculators useful. They sure would have been useful to me in my design laboratory days, years ago now.
Also, suggested improvements are welcome. I've tried to make everything intuitive, but other views will be appreciated.

I expect you'll let me know if the answer to your calculation seems to be wrong!

More calculators are in development - if you use an equation suitable for a calculator, I'd like to hear from you.

My email address is sparks@cvs1.co.uk - I look forward to receiving your comments.
