The ideal OP-AMP has the following characteristics
Correct answer: A. Ri=∞ ,A=∞ ,R0=0
- A. Ri=∞ ,A=∞ ,R0=0
- B. Ri=0 ,A=∞ ,R0=0
- C. Ri=∞ ,A=∞ ,R0=∞
- D. Ri=0 ,A=∞ ,R0=∞
Explanation
An ideal op-amp draws no input current, has infinite open-loop gain, and has zero output resistance. These correspond to Ri = ∞, A = ∞, and R0 = 0.
