So my question is simple.
If the current doesn't change sign, is it considered AC or DC?
I seem to recall we called it DC when I briefly saw it.
However after a quick google search I'm confused. Some said that for example an AC signal offset with a DC signal to show this behaviour should be called AC because there is an AC component.
But then there was the odd example of a capacitor discharging. I absolutely do not agree with that being an AC signal.
In fact I'm reluctant to accept the first one too. Say we have 2 DC sources which we can add together.
If we let one of them be turned on and off periodically (simple example would be an on/off switch).
How can you say it's got an AC component there?
Is there any consensus on this problem of nomenclature?
