wire resistance

[Dixix]

Hello all together
Sorry for my stupid question: How can I calculate the wire resistance and length. Example: I have 0.4mm Copper wire and need a wire resistance of 2.8 ohms. How many meters of wire do I need?
Thanks for the help
Dirk

Hello Bernd Thank you for the quick reply! Genial! The websites in my native language. Here is all I want to know. Even calculator for the lazy like me. I want to work their way up the theme coils. A good detector stands and falls with its coil! Is a difficult issue, especially the shield. But also the cable to the coil. I try on here for some days. Test, test, test .... Various coils: Basket-coil, normal coils , flat coils and so on. All of Bernard's "PICKINI" PI- detector. All the best, Dirk
