The op amp in the non inverting amplifier circuit of Figure 1 has an input resistance of 560 kΩ an output resistance of 8kΩ, and an open-loop gain of 50,000. Assume that the op amp is operating in its linear region.

a) Calculate the voltage gain (υo / vg).

---

b) Find the inverting and non inverting input voltages υn and υp (in millivolts) if υg = 1V.

---

c) Calculate the difference (υp - vn) in microvolts when υg = 1 V.

---

d) Find the current drain in picoamperes on the signal source υg when υg = 1V.

---

e) Repeat (a)-(d) assuming an ideal op amp.
