Calculating Gain without Feedback and Feedback Factor

Gain without Feedback:
- Let's denote the gain without feedback as A.
- The gain with feedback is given by A = Vout/Vin.
- Without feedback, the output voltage is 20V and the input voltage is 0.5V.
- Therefore, A = 20V / 0.5V = 40.

Feedback Factor:
- Let's denote the feedback factor as B.
- The feedback factor is given by B = 1/(1 + A).
- After removing feedback, it requires 0.25V for the same output of 20V.
- Therefore, A = 20V / 0.25V = 80.
- Now, we can calculate B: B = 1 / (1 + 80) = 1/81.

Explanation:
- The gain without feedback is the ratio of output voltage to input voltage when there is no feedback loop in the system. In this case, the gain without feedback is 40.
- The feedback factor is the fraction of the output voltage that is fed back to the input. In this case, the feedback factor is 1/81.
- These values are important in understanding the behavior of the system and designing circuits for specific applications.
