OHM's LAW

Answer the given problem. Show solution. (If it's handwritten it should be readable,understandable and clear ty.)

A. Silver is composed of 5.8 x 1028 free electrons per cubic meter. If a silver wire with a diameter of 1.8 mm can allow charges of 360 C to ow in 1 hour, a. What is the current in the conducting wire? b. What is the magnitude of the drift velocity of the electrons in the conducting wire? B. A wire has a radius of 1.90 mm. If the current in the Wire is 6.14 A, the drift velocity is 4.86 X 105 m/S. What is the concentration of free electrons in the meta]? C. The terminal voltage of the battery in figure 4 is 16.6 V. What is the resistance R of the external resistor? What is the internal resistance r of the 18.0-V battery? 18.0 V 3.00 A 3.00 A RD. What should be the diameter of an aluminum wire for its resistance to be equal to that of a copper wire which diameter is 2.17 mm? The two wires are of the same length. p(Copper) = 1.68 x 10'8 - m p(Aluminum) = 2.65 x 10'8 - m
