4.16. The variable resistor R, in the circuit in Fig. P4.16 is adjusted until the source current ig is zero. The op amps are ideal, and 0 ≤ vg ≤ 1.2 V. (a) What is the value of Ro? (b) If v₂ = 1.0 V, how much power (in mi- crowatts) is dissipated in Ro? + 20 ΚΩ Vg Figure P4.16 80 k 5 V -5 V Ro 10 ΚΩ ww 16 ΚΩ M 10 V -10 V 40 ΚΩ
