Question

Quizplus · Accepted Answer

A Josephson junction consists of two superconductors separated by a thin insulating barrier known as the Josephson junction. The junction allows for the flow of supercurrent and can be used in various applications such as voltage standard and superconducting circuits. B, C, and D are incorrect as they don't describe the structure of a Josephson junction accurately.
