2.18 In the circuit of Fig. P2.17, what is the current flowing through the output of the ideal op amp? If we wish to use a practical op amp that has a specified maximum output current of 2.5 mA, how may the values of the resistors R1 and R2 be changed so that the gain remains the same? 3 mA; R1 = 2 kΩ; R2 = 20 kΩ
