PHY2061 R. D. Field Problems Chapter 29 Page 1 of 1 Chapter 29 Problems Problem 1: Wire B is three times longer than wire A , and the two wires have the same volume . If both wires are made of the same substance and if the resistance of wire A is 9 Ohms , what is the resistance of wire B ( in Ohms ). Problem 2: Consider a long straight cylindrical wire with radius R carrying the non- uniform current density, J(r)=ar 2 , where r is the distance from the center

Unformatted text preview: axis of the wire. How much total current I passes through the wire? Problem 3: Consider a long straight cylindrical wire with radius R = 0.1 m is carrying the non-uniform current density which points along the axis of the wire and has a magnitude, J(r) = a/r , where r is the distance from the center axis of the wire. If a = 2 A/m , how much total current I passes through the wire ( in A )?...
