Chapter 27, Problem 012 The figure shows a resistor of resistance R = 6.05 12 connected to an ideal battery of emf 8 = 13.3 V by means of two copper wires. Each wire has length 23.2 cm and radius 4.20 mm. In dealing with such circuits in this chapter, we generally neglect the potential differences along the wires and the transfer of energy to thermal energy in them. Check the validity of this neglect for the circuit of the...
