### Op Amp in Noninverting Amplifier Circuit

**Figure P5.47:**

This figure illustrates a noninverting amplifier circuit using an operational amplifier (op amp). The input voltage \( v_g \) is connected through a 15 kΩ resistor to the non-inverting input of the op amp. The inverting input is connected to the output \( v_o \) through a 135 kΩ feedback resistor. The power supply voltages for the op amp are +6 V and -6 V.

**Key Parameters:**
- Input resistance: 400 kΩ
- Output resistance: 5 kΩ
- Open-loop gain: 20,000

**Tasks:**

a) **Calculate the Voltage Gain (\( v_o/v_g \)):**

   Determine the voltage gain of the op amp circuit in the noninverting configuration.

b) **Find the Inverting and Noninverting Input Voltages (\( v_n \) and \( v_p \)):**

   Compute the values of the inverting (\( v_n \)) and noninverting (\( v_p \)) input voltages in millivolts if the input voltage \( v_g = 1 \) V.

#### Questions and Exercises

**c) Calculate the difference (\(v_p - v_n\)) in microvolts when \(v_g = 1 \, \text{V}\).**

**d) Find the current drain in picoamperes on the signal source \(v_g\) when \(v_g = 1 \, \text{V}\).**

**e) Repeat (a)–(d) assuming an ideal op amp.**

#### Diagram Description

**Figure P5.48:**

- A circuit diagram illustrating an operational amplifier setup.
- Components and Connections:
  - **Resistors:**
    - 80 kΩ
    - 40 kΩ
    - 100 kΩ
    - 4 kΩ (connected to the output \(v_o\))
  - **Operational Amplifier:**
    - Voltage supplies of +18 V and -18 V.
    - Input from source \(v_g\).
    
This circuit demonstrates the use of an op-amp in a configuration with various resistors and dual voltage supplies, typically used for amplification or signal processing tasks.

### Additional Exercise

**5.49 Practical Perspective:**

- **Scenario:** Suppose the strain gages in the bridge in Fig. 5.22 have the value of 120 Ω ± 1%. The power supplies to the op amp are ±15 V, and the reference voltage, \(v_{\text{ref}}\), is taken from the positive power supply.

**a) Calculate the value of \(R_f\) so that when the strain gage is lengthening reaches its maximum and the output voltage is 5V.**

This exercise involves determining the feedback resistor \(R_f\) required to achieve a desired output voltage in a strain gage setup, given specific power supply and reference conditions.
