What is the primary assumption made about an ideal operational amplifier?.
- A.It has a finite input impedance
- B.It has zero output impedance
- C.It has infinite bandwidth
- D.It has a non-linear response
Model answer
What a good answer should say
- It has infinite bandwidth
Explanation
Why this works
One of the primary assumptions of an ideal operational amplifier is that it has infinite bandwidth, meaning it can amplify signals of any frequency without attenuation. This idealization allows for simplified analysis and design of circuits using op-amps.
