Question: 1. A silver wire 1 mm in diameter transfer a charge of 90 C in 1 hr and 15 min. Silver contains 5.8x1028 free

1. A silver wire 1 mm in diameter transfer a charge of 90 C in 1 hr and 15 min. Silver contains 5.8x1028 free electrons per m. a) What is the current in the wire? b) What is the drift velocity of the electrons in the wire? 2. An aluminum wire having a cross-sectional area equal to 4.00x106 m carries a current of 5.00 A. The density of aluminum is 2.70 g/cm. Assume each aluminum atom supplies one conduction electron per atom. Find the drift speed of the electrons in the wire.
