When the non-inverting input terminal of an op-amp is equal to that of the inverting input terminal (ideally)
A. a–>∞
B. Vid ≅ 0
C. AF = 1+( RF / R1)
D. All of the mentioned
Answer:A
When the non-inverting input terminal of an op-amp is equal to that of the inverting input terminal (ideally)
A. a–>∞ B. Vid ≅ 0 C. AF = 1+( RF / R1) D. All of the mentioned
Explanation: When the input at both the terminal are equal, the difference input voltage, Vid=Vin1– Vin2.
