The circuit shown in Fig. 3.64 includes a
device known as an op amp. This device has
two unusual properties in the circuit shown:
(1) Vd = 0 V, and (2) no current can flow into
either input terminal (marked "-" and "+"
inside the symbol), but it can flow through the
output terminal (marked "OUT"). This
seemingly impossible situation-in direct
conflict with KCL-is a result of power leads to
the device that are not included in the
symbol. Based on this information, calculate
Vout. (Hint: two KVL equations are required,
both involving the 5 V source.)
