For an ideal negative feedback configuration which of the following is...
Virtual Short Circuit in Negative Feedback Configuration:
Negative feedback configuration in an amplifier is designed to reduce distortion and improve stability. In this configuration, the feedback signal is subtracted from the input signal to produce the output signal. One key characteristic of an ideal negative feedback configuration is the presence of a virtual short circuit between the input terminals.

Explanation:
- In an ideal negative feedback configuration, the feedback signal is injected into the input signal with a phase shift of 180 degrees. This results in a virtual short circuit between the input terminals.
- The virtual short circuit at the input terminals ensures that the input signal is effectively canceled out by the feedback signal, reducing distortion and improving linearity.
- This virtual short circuit also helps in stabilizing the amplifier by reducing the gain and preventing oscillations.

Key Points:
- Virtual short circuit between the input terminals is a characteristic of an ideal negative feedback configuration.
- It helps in reducing distortion, improving linearity, and stabilizing the amplifier.
- The presence of a virtual short circuit ensures that the feedback signal effectively cancels out the input signal.
By understanding the concept of a virtual short circuit in a negative feedback configuration, one can design and analyze amplifier circuits effectively in the field of electrical engineering.
