So, I need to find how much resistance or current there is in my wire. The voltage running through it is 6 volts. It's wrapped around a 3-1/2 inch iron nail, and the wire itself is a thinly insulated copper knife. There are 28 total coils of the wire. The wire is roughly 3-1/2 feet long. I know that Voltage=Current*Resistance, but I only know the voltage. I don't know the current, and I could find it if I knew the resistance. Can anyone help me with this? It's hard to do.
