drvrm said:pl. look up the following and point out at which stage of the working of the J Junction you felt like "a perpetual motion system "?

A Josephson Junction is a device made of two superconducting materials separated by an insulating layer. It allows for the flow of supercurrent, which is the current that flows without any resistance.
The Josephson Junction works by exploiting a quantum mechanical effect known as the Josephson effect. This effect allows for the flow of supercurrent between the two superconducting materials, as long as they are at a specific temperature and have a specific voltage applied to them.
No, a Josephson Junction cannot be used for perpetual motion. While it does allow for the flow of supercurrent without resistance, it still requires energy to function and cannot create an infinite amount of energy.
Josephson Junctions have potential applications in quantum computing, precision measurements, and high-speed signal processing. They are also used in devices such as superconducting quantum interference devices (SQUIDs) and superconducting quantum bits (qubits).
Yes, there are limitations to the use of Josephson Junctions. They require extremely low temperatures and precise voltage control to function, which can be challenging and expensive to achieve. Additionally, they are sensitive to external magnetic fields, which can interfere with their operation.
