In an inverting operational amplifier circuit with an input resistance of 2 kΩ and a feedback resistance of 5 kΩ, if the input voltage Vi = 0.5 V, find the output voltage V0 and the current I flowing through the 10 kΩ load resistance connected at the output.
- 1V0 = -1.25 V, I = 125 μA✓
- 2V0 = -0.40 V, I = 20 μA
- 3V0 = -0.40 V, I = 50 μA
- 4V0 = -1.25 V, I = 20 μA
Correct answer
V0 = -1.25 V, I = 125 μA
