Can someone please explain why ideal voltage/current sources are short circuit for voltage source and open circuit for open circuit in small signal analysis? Any mathematical proof to this?

An ideal voltage/current source is a theoretical concept used in electrical engineering and physics. It is a source of electrical energy that maintains a constant output voltage or current regardless of the load connected to it.
The main characteristics of an ideal voltage/current source include having no internal resistance, providing a constant voltage or current regardless of the load, and being able to supply an infinite amount of power.
Ideal voltage/current sources are useful in circuit analysis and design because they simplify complex circuits and allow for easier calculations. They also serve as a reference for real-world voltage/current sources.
No, ideal voltage/current sources are purely theoretical and do not exist in the real world. However, some devices such as batteries and power supplies can closely approximate ideal sources under certain conditions.
Ideal voltage/current sources are idealized models and do not take into account real-world factors such as internal resistance, power limitations, and variability in voltage or current output. They also cannot account for fluctuations in the load connected to them.
