The -iR is easy as it is a potential drop in the direction of the current.
The idea of calling the potential across the inductor as always -Ldi/dt
when trasversing in the direction of the flow is far less intuitive. It is
so clearly a potential gain in the decay circuit that I have a hard time
writing a negative. It does work and I recognize the fact that the -di/dt
makes the term positive ( which is how I made the derivation work in class
on Friday) but it seems more like memorizing a rule than not.
