Ideally OP-AMPS have ______ input resistance ans ______ output resistance

  1. infinite and zero

  2. infinite and infinite

  3. zero and infinite

  4. zero and zero
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Ideal op-amps are designed with infinite input resistance so they draw no current from the source (no loading effect), and zero output resistance to act as a perfect voltage source that can drive any load without voltage drop. Option B incorrectly suggests both are infinite, while option C reverses the ideal properties.
