Question:

Equation (11.11.13) was deduced neglecting the associated parallel resistance of the junctions, which shown in Figure 11.23(a). Rewrite this equation for the case in which each junction has a parallel resistance R, and determine the maximum voltage drop ±V across the SQUID shown in Figure 11.22 for the case of constant input current I, as a function of the magnetic flux ´ through the loop.
