As shown in figure "A" of the illustration, what is the configuration of the operational amplifier? EL-0252
Official USCG Answer & Rule Citation
Correct Answer: Option D — inverting amplifier
The inverting amplifier configuration is characterized by the input signal being applied to the inverting input (marked with a minus sign) through a resistor, while the non-inverting input is grounded. This setup produces an output signal that is 180 degrees out of phase with the input, as per standard operational amplifier theory.
