What is one of the ideal assumptions of an operational amplifier?.
- A.The input impedance is infinite
- B.The output impedance is infinite
- C.The gain is zero
- D.The bandwidth is limited
Model answer
What a good answer should say
- The input impedance is infinite
Explanation
Why this works
One of the ideal assumptions of an operational amplifier is that its input impedance is infinite, which means it does not draw any current from the input signal, allowing for accurate signal processing.
