Wire 1 is made of a material with resistivity p. The diameter of wire 1 is D, the length is L and the resistance is R. Wire 2 is made from a material with a resistivity 2p and the wire has a diameter 2D. What length must wire 2 have so that its resistance is the same as that of wire 1? A. L/2 B. 2L C 4L D. L/4 E 8L
