Eight copper wire of length l and diameter d
WebQuestion. Transcribed Image Text: Nine identical wires, each of diameter d and length L, are connected in series. The resistance of the other wire (length L) is the same resistance as the equivalent combination of 9 wire. The diameter of this wire is: 18d d/18 d/3 2d 9d d/81 none of the above d/2 3d 6/p. Web: (a) A 34.5m length of copper wire at 20.0°C has a radius of 0.25 mm. If a potential difference of 9.0V is applied across the length of the wire, determine the current in the wire. (b) If the wire is heated to 30.0°C while the 9.0V potential difference is maintained, what is the resulting current in the wire? Resistivity of Cu =1.72×10 −8
