Question
**Question 5** The input resistance in the circuit in Fig. 1 where the op-amp is ideal is **Figure 1 Description:** The diagram shows an operational amplifier (op-amp) circuit. The ideal op-amp is represented by a triangle with a positive (+) and negative (-) input. The following components are connected: - Two 1 kΩ resistors are connected in series with the input voltage \( v_{\text{in}} \) leading to the negative terminal of the op-amp. - Another 1 kΩ resistor is connected from the negative terminal of the op-amp to the ground. - A feedback resistor (2 kΩ) connects the output \( v_0 \) back to the negative terminal of the op-amp. - The positive terminal of the op-amp is connected to the ground. **Options:** - a. 0.5 Kilo-Ohms - b. 1 Kilo-Ohm - c. 2 Kilo-Ohms - d. Infinite
