Hello! I am a beginner in English terminology.

I know that direct current is a flow of electricity that moves in one direction only (i.e. does not change its direction).

I also know that alternating current is an electric current that reverses direction at regular intervals.

However, I cannot find in my dictionaries the proper English terms for:

1) a DC current, which does not change its intensity at all,

2) a current, which does change its intensity, but not necessarily its direction (that is, the general term for AC, pulsating DC, DC smoothly petering out etc.)

I find several word combinations, which may or may not be the right terms:

1) steady current, constant current, time-independent current, stationary current;

2) time-dependent current, time-varying current, variable current.

Which are the standard (conventional) terms, OK but awkward terms and wrong (misleading) terms?

Is there any authoritative source in English (a textbook, an encyclopedia, a standard etc.) which I can quote when discussing these terms with my compatriots?

If you don't know the standard names, what do YOU call these currents?
