An inverting amplifier with gain 1 having different input voltage 1 V, 3.3 V and 4.3 V. Find the output voltage?

To find the output voltage of an inverting amplifier with a gain of 1, we can use the formula:

Vout = -Vin * Rf / Rin

Where Vin is the input voltage, Rf is the feedback resistor, and Rin is the input resistor.

Since the gain is 1, the feedback resistor (Rf) and the input resistor (Rin) are equal. Let's assume they have a value of R.

For an input voltage of 1 V: Vout = -1 * R / R = -1 V

For an input voltage of 3.3 V: Vout = -3.3 * R / R = -3.3 V

For an input voltage of 4.3 V: Vout = -4.3 * R / R = -4.3 V

Therefore, the output voltage for input voltages of 1 V, 3.3 V, and 4.3 V is -1 V, -3.3 V, and -4.3 V, respectively.
