Hello, Please include ALL steps and Final COMPUTATION so I canunderstand and compare to what I have worked on. Thanks.
A power station uses a copper bus bar to conduct large amountsof current. The bar is 1.9 m long and 8.3 cm by 3.5 cm in crosssection. What voltage applied to the ends of the bar willproduce a 2100 A current through it?
V

V

Explanation / Answer

Area of cross-section of the bar,
         A =8.3x3.5 = 29.05cm2 = 29.05x10-4 m2 Resistivity of copper, = 17 n.m =17x10-9 . Resistance of the bar,      R = L/A= 17x10-9 x 1.9/29.05x10-4            =1.112x10-5 Voltage required,           V = IxR= 2100x1.112x10-5             = 2.334x10-2 V = 0.0233 V = 23.3 mV Resistivity of copper, = 17 n.m =17x10-9 . Resistance of the bar,      R = L/A= 17x10-9 x 1.9/29.05x10-4            =1.112x10-5 Voltage required,           V = IxR= 2100x1.112x10-5             = 2.334x10-2 V = 0.0233 V = 23.3 mV
