No. Phase applies to AC.

No, phase only has meaning for cyclical phenomena. Phase in electricity refers to the proportion of a cycle by which the voltage peaks of of the different lines are offset. In two phase AC, the phase difference is 180°, meaning that the peak in the one line is half a cycle after the other. In three-phase power, each line is 120°, or a third of a cycle, out of phase with the next.

Nope, DC voltage, by definition does not have a cyclical nature, hence no period and so, a point in the signal's period can not move forward or backward relative to the start of the period to suggest the notion of phase in a DC voltage signal. Phase in an AC signal (for example, a sinusoidal wave) simply means that a point that repeats itself on every period happens at a given amount of degrees from 0 degrees (the start of the period). For example, if an AC signal's 0 degree point were to happen ar one quarter of it's period, the phase of that signal would be 90 degrees (360 degrees, or a whole period divided by four - a quarter of the period).

What your professor is calling is amazingly extremely effortless. First imagine of a stand DC generator. The winding's will produce a common sinusoidal AC voltage which will then be rectified with the help of a commutator. So the output will seem as if a series of "humps". including an extra effective section that is ninety tiers out of section with the first will merely upload yet another set of humps to the output. the overall effect will create a smother output out of your generator. In software actual DC turbines use 1000's of winding's to create an particularly comfortable output. desire this facilitates!

No. AC can be dual phase, in which the current changes direction, or single phase, with pulses of electrons all travelling in the same direction.

Yes. It does exist. But its only ONE PHASE =)

Phase for DC has no meaning. So: no.

It wouldn't phase me.

No period => no phase
