If Vin= 10V find Vout 

The image is a schematic diagram of an electrical circuit involving operational amplifiers (op-amps) and resistors. Below is a detailed transcription and explanation of the circuit:

**Components and Connections:**

1. **Resistors:**
   - R1: 10 kΩ
   - R2: 10 kΩ
   - R3: 20 kΩ
   - R4: 20 kΩ
   - R5: 10 kΩ
   - R6: 10 kΩ
   - R7: 20 kΩ

2. **Operational Amplifiers:**
   - Three op-amps are represented by triangular symbols with two inputs (positive and negative) and one output.

**Circuit Description:**

- The input signal enters the circuit through resistor R1, which is connected to the inverting input (-) of the first op-amp. The non-inverting input (+) is grounded.
- The output of the first op-amp is connected via resistor R2 to the inverting input of the second op-amp. The non-inverting input of this op-amp is also grounded.
- The output of the second op-amp feeds back through resistor R3 to its inverting input.
- Resistor R4 connects the output of the second op-amp to the inverting input of the third op-amp.
- The output of the third op-amp provides the final output signal.
- Feedback from the third op-amp's output goes through resistors R6 and R7 back to the inverting input of the third op-amp.
- A feedback loop with resistor R5 is present from the output of the third op-amp to its own inverting input, enhancing stability and performance.

**Circuit Functionality:**

- The configuration forms a series of inverting amplifier stages, where each op-amp, in collaboration with the surrounding resistors, carries out amplification and signal processing.
- The resistor values govern the gain and frequency response of the circuit, providing signal conditioning suitable for various applications within educational or experimental contexts.

This schematic can be useful for understanding concepts of signal amplification, feedback, and operational amplifier characteristics in electronics education.
