Explanation Given: The value of the output voltage of the op-amp is v o = 4.0 V . The value of the input voltage to the op-amp is v i = 1.0 V . The given circuit diagram is shown below. Figure 1 Calculation: The input voltage to an op-amp is the difference between the voltage at the inverting terminal ( V + ) and the voltage at the non-inverting terminal ( V − ). Therefore, the following equation can be written as V i = V + − V − ( 1 ) Since the inverting terminal is grounded, the value of the voltage at the inverting terminal will be V − = 0 V . From voltage divider rule, the value of the voltage at the non-inverting terminal will be V + = v i × 1 k Ω 1 k Ω + 1 M Ω = 1 × 10 3 10 3 + 10 6 = 0

Operational Amplifier

An operational amplifier also called op amp is an integrated circuit or analog circuit that takes input as a differential voltage and produces output as a single-ended voltage. It is an IC that can amplify weak electric signals.An op amp has one output p…
