Chapter 4.6, Problem 3E

Interpretation Introduction

Interpretation:

Potential corresponding to the given equation is to be found, the potential is to plotted as a function of $\varphi$. To analyze the effect on the potential as value of I increases

Concept Introduction:

The superconducting devices which are capable of generating voltage oscillations of very high frequency (${10}^{10}-{10}^{11}$ cycles per second) are called as Josephson junctions.

Construction of Josephson junctions is two closely spaced superconductors separated by a weak connection.

The Josephson current-phase relation is

${\text{I = I}}_{\text{c}}\sin \varphi$, where I and I_c are current through junction and critical current respectively.
