Question

Consider the following circuit: Suppose the input voltage Vin=1mV. Which of the following statements is/are true? The opamp is ideal. The op-amp is used as a buffer to increase the voltage from the source to the load. Iout = 0 The op-amp is used as a buffer to supply more power to the load than can be supplied by the source. Vout = 3V Iin = 0

Step 1

If the op-amp is ideal, it means that it has infinite input impedance, zero output impedance, and infinite gain. This means that no current flows into the op-amp (Iin = 0), which is one of the statements given. Show more…
