Questions: A certain copper wire has a resistance of 10.0 Ω. At what fraction of the length L must the wire be cut so that the resistance of one piece is 5.0 times the resistance of the other?
What is the resistance of the longer piece? Shorter piece?
I am completely lost on this. i know it should be fairly simple and I think I have to use the equation R= p*l/A
