calculate the resistance of a copper wire 1.0km long and 0.50 mm diameter if the resistivity of copper is 1.7 x 10( 10 to the power -8 ) ??
2. The resistance of a metal wire of length 1m is 26 ohms at 20'c .If the diameter of the wire is 0.3mm, what will be the resistivity of the metal at that temperature ????
