Can a device store energy if L is a constant?

If L is a constant (which is often dt dt dt true) then v = L di which means vdt = Ldi, which we can substitute dt into the equation for Energy above yielding: which in all likelihood you will have seen before in a physics class. In both of these cases, the device can store energy and therefore its source-like constitutive relation makes some sense.

Principle of Energy Storage Switch | Quisure Circuit Breaker

The so-called energy storage means that when the circuit breaker is de-energized (that is, when it is opened), it opens quickly due to the spring force of the energy storage switch. Of course, the faster the circuit breaker is opened, the better. This is to have enough power to separate the contacts when the segmentation fault has a large current (excessive current will melt the
