Exam-style question
Try this first
Which assumption about an ideal operational amplifier relates to its output?.
- A.The output can drive any load
- B.The output impedance is zero
- C.The output voltage is always zero
- D.The output current is infinite
Model answer
What a good answer should say
- The output impedance is zero
Explanation
Why this works
An ideal operational amplifier assumes that its output impedance is zero, allowing it to drive loads without any voltage drop across the output terminals.
