Op Amp As A Amplifier

Step 1: Identify configuration.
The given op-amp circuit is a non-inverting amplifier. The input voltage is applied to the non-inverting terminal through a voltage divider formed by the two resistors connected to the source.
Step 2: Determine voltage at non-inverting terminal.
Since the two resistors are equal, the voltage at the non-inverting terminal is Step 3: Apply virtual short condition.
In an ideal op-amp,
Step 4: Compute output voltage using voltage divider in feedback loop.
For the feedback network with two equal resistors of , However, note that there is another resistor at the inverting input connected to the input source (forming a non-inverting amplifier with gain ). Thus, Step 5: Final Answer.
Hence,
