Write a function def dianeter (wire_gauge) that accepts the wire gauge and returns the corresponding diameter. Write another function def copper wire resistance(length, wire_gauge) that accepts the length and gauge of a piece of copper wire and returns its resistance. The resistivity of aluminum is (2.82108mm). Write a third function def aluainum_wire_resistance(length, wire_gauge) that accepts the length and gauge of a piece of aluminum wire and returns its resistance. Then write a program to test these functions
