Toy Josephson Coupling

Current Times Flux Is an Energy Budget

The toy coupling surface is an exact current-flux energy ledger. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

Current times flux has energy units

A current of 3 amperes and flux 2 webers give toy coupling energy 6 joules.

The coupling is a normalized training contract

The checked value 6 joules is not a real device formula; it is only the toy current-flux budget.
