Question: What is the typical input impedance of an ideal operational amplifier?

Options:

Correct Answer: Infinity

Solution:

An ideal operational amplifier has infinite input impedance, meaning it draws no current from the input source.

What is the typical input impedance of an ideal operational amplifier?

Step 1: Understand what an operational amplifier (op-amp) is. It is an electronic device used to amplify voltage signals.
Step 2: Learn about input impedance. Input impedance is a measure of how much resistance an op-amp offers to the input signal.
Step 3: Know that an ideal op-amp is a theoretical concept. It has perfect characteristics, including infinite input impedance.
Step 4: Realize that infinite input impedance means the op-amp does not draw any current from the input source.
Step 5: Conclude that because it draws no current, it does not affect the input signal, making it ideal for many applications.
