Question

An ideal op-amp has the characteristic of an ideal:

• A. Voltage controlled voltage source
• B. Voltage controlled current source
• C. Current controlled voltage source
• D. Current controlled current source

Hint:

An ideal op-amp = VCVS: output voltage depends on input voltage difference.

Answer 1

The Correct Option is A

An ideal operational amplifier amplifies the difference between its two input voltages and outputs a voltage. It has:
- Infinite input impedance,
- Zero output impedance,
- Infinite gain.
Thus, it acts as a **voltage controlled voltage source (VCVS).**
