A 2 ohm resistance coil is to be constructed from a wire of diameter0.35 mm. If the resistivity of constantan is 4*10^-6 ohm cm, what is the length of the wire required to construct the coil? A copper wire has a diameter of 0.5 mm and resistivity of 1.6×10 to the power of -8 ohm meter

mumtazmohan: I am sorry, but isn't that not the answer?

mumtazmohan: It is 2.8 x 10 to the power of -6 ohm metre
