Question:medium

In the ideal case, what is the input impedance of an operational amplifier?

Show Hint

Ideal Op-Amp parameters to memorize: - Input Impedance = \(\infty\) (Draws zero current, prevents source loading). - Output Impedance = \(0\) (Can supply unlimited current to any load without a voltage drop).
