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...

The figure shows a rod of length L = 7.85 cm that is forced to move at constant speed v = 7.10 m/s along horizontal rails. The rod, rails, and connecting strip at the right form a conducting loop. The rod has resistance 0.393 2; the rest of the loop has negligible resistance. A current i = 112 A through the long straight wire at distance a = 13.6 mm from the loop sets up a (nonuniform) magnetic field throughout...
R, Figure P7.49 .50 Figure P7.50 shows a current source realized using a current mirror with two matched transistors Q, and o, . Two equal resistances R, are inserted in the source leads to increase the output resistance of the current source. If Q, is operating at gm 1 mA/V and has VA-= 10 V, and if the maximum allowed de voltage drop across R, is 0.3 V, what is the maximum avail- able output resistance of the current source?...
