Three quick points of nomenclature about which I'd like to hear the
opinions of the list:
(1) Do you use "dc" and "constant current" as synonyms or not? eg. Is
I0*exp(-t/T) direct, since it never reverses direction? If so, the
sum of two dc values is not in general dc. That seems odd to me, but
if's that the accepted convention I can live with it.
(2) In light of your answer to (1), what does the term "quasi-dc" mean?
(3) Do you use "ac" to refer to things like voltage and the like
which are not currents?
