When two superconducting regions are weakly coupled, a Josephson junction (JJ) can be formed by placing a thin insulating gap between the two superconductors. Electron pairs can tunnel through this gap and a resistance less current can f ...

... Voltmeter measures voltage drop across resistance by putting it in parallel to the resistance as shown in Fig 1. The internal resistance of a voltmeter is quite high (Rm ≫ R) and, therefore, when connected in parallel the current through the voltmeter is quite small (iv ≈ 0). This keeps the current ...
