The current shall be described as alternating. 
The current shall be described as cycling both positive and negative. 
The circuit MUST be defined as either alternating current or direct current.
What would you define this circuit as?

rich, voltage in circuits can also be DC with an AC component or AC with a DC component, many times an AC component is undesirable in a DC circuit. This capacitors current is definitely AC. The Voltage could be classed either as pulsating DC or more correctly AC because while it has a DC components (bias), the current is AC and would continually affect a capacitive or inductive circuit.

These questions are not for me, there for you and the community. I'm nobody's instructor. So I will only ask questions in hope you can form logic.

The next question: If Tesla was the innovator of AC. And Edison same for DC. Who is this inventor for this "pulsed DC classification" that conveniently self classified itself as "DC"??? Hint: The arduino I/O is 5vdc, not 1.76 VAC.

It's. an AC signal , basically any signal which changes with respect to time and has a definite time period for a complete cycle is Alternating in nature

My 555 is DC though. It is polarity sensitive. Same for the super capacitor. Their electrons receive only positive charges on their positive terminals. This circuit contains only positive electrons, it can operate the same way reversed biased with negative electrons. The component will fail if the wrong charge is applied. A components charge can only be referenced at the component, it doesn't care where the ground reference is.

+1-1=0 this means 0 is the reference. If it is in the middle, the -1 and +1 alternates symmetrically about 0. Thus an alternating " current " or anything I'd either symmetrical or not. The reference is nothing to do with alternation. Even a dc. Voltage is measured with respect to 0. The capacitor is generating a negative spike, it has to go somewhere!!!! ( back to the supply voltage. There are lots of numbers ( infinite) but only one zero.

The question is,,,, is zero a number?!!!!!!
