What is the result of applying a small input voltage to an ideal op-amp in open-loop configuration?.
- A.No output voltage
- B.A small output voltage
- C.A large output voltage
- D.An oscillating output voltage
Model answer
What a good answer should say
- A large output voltage
Explanation
Why this works
In an ideal operational amplifier, applying a small input voltage results in a large output voltage due to the infinite open-loop gain. This characteristic leads to saturation, where the output reaches its maximum or minimum limit, demonstrating the op-amp's sensitivity to input changes.
