Conclusion:

Thus, the five op-amp terminals with their names are labeled as shown in Figure 1.

(b)

To determine

Mention the ideal op amp constraint that determines the value of in and also mention the value of in.

Answer to Problem 1P

The input resistance of the op amp constraints determines the value of in and the value of current in is 0A.

Explanation of Solution

Discussion:

The input resistance available at the input terminals will determines the current value in. The input resistance of an ideal op amp is infinite, which constraints the value of the input currents to zero. Hence, the value of current in=0A.

Conclusion:

Thus, the input resistance of the op amp constraints determines the value of in and the value of  current in is 0A.

(c)

To determine

Mention the ideal op amp constraints that determines the value of (vpvn) and also mention the value of (vpvn).

(c)

Answer to Problem 1P

The open loop voltage gain of the op amp constraints the value of (vpvn) and the value of (vpvn) is 0V.

Explanation of Solution

Discussion:

The open loop voltage gain of an ideal op amp determines the value of (vpvn). The open loop voltage gain of an ideal op amp is infinite, which constraints the difference between the voltage that appear across the inverting and non-inverting terminal of the op amp to 0 V. Therefore, the value of vpvn=0V.

Conclusion:

Thus, the open loop voltage gain of the op amp constraints the value of (vpvn) and the value of (vpvn) is 0V.
