Question

Calculate vo in the op amp circuit. Given that vs = 6.7 V. The output voltage is__V.

Answer 1

The output voltage
`\(v_o\)` in the op amp circuit, given that
`\(v_s = 6.7 \ \text{V}\)`, is 0 V.

Step-by-step explanation:

In an ideal operational amplifier (op amp) circuit with negative feedback, the voltage at the inverting (-) and non-inverting (+) terminals is virtually the same. Therefore, the potential at the inverting terminal is also
`\(6.7 \ \text{V}\).` This implies that the voltage drop across the resistor \
`(R_2\)` is zero since both its ends are at the same potential.

The output voltage
`(\(v_o\))` is determined by the voltage difference between the inverting terminal and the ground. However, since the inverting terminal is at the same potential as the ground,
`\(v_o\)` is zero. This is a characteristic behavior of an op amp in an ideal configuration with negative feedback.

In summary, the output voltage
`(\(v_o\))` is 0 V in this op amp circuit when
`\(v_s\)` is 6.7 V, reflecting the ideal behavior of an op amp with negative feedback.
