1) a) A wire sample (1 mm in diameter by 1 m in length) of an aluminum alloy (containing 1.2% Mn) is placed in an electrical circuit such as that shown in the figure below. A voltage drop of 432 mV is measured across the length of the wire as it cames a 10 A current. Calculate the electrical conductivity of this alloy -Length,/ Area, A Sample geometry b) Copper has an electrical conductivity of 58.00 x 106 S/m and a free electron density of 104 x 1027m²³. Calculate the drift velocity of these electrons under an electric field of 0.5 V/m.
