Often the Anode or Cathode sun is the main topic.
Also, the sun is described as a "discharge" to the Heliosphere.
And, it is said that the poles of the sun receive the main power behind the discharge etc.
I offer here a different mix of views and ideas of the EU:
I think the fundamental structure of the sun is the "quiet sun."
The sun is Organic in the sense that is self organized plasma, condensed in from the heliosphere (where the plasma density is 1/40 of the interstellar density outside the heliosphere). The plasma "drifts in" (Dr Scott) and ultimately forms the double layer above the photosphere(Dr Scott again). This spherical double layer(chromosphere) isolates the trapped plasma below ( the solar granules appear to rise, roll over and return ) from the plasma that is the very bottom of the corona. Thus the relatively calm electrical environment of the solar interior is separated from the bottom of the hot chaotic corona. But, there is also a direct and orderly transfer of energy through the chromosphere(the lowest temperatures of the sun structure = orderly current flow) to maintain the proper voltage and charge at the photosphere and below.
There may be special current at the poles of the sun but, I think the main power of the sun is delivered directly through the chromosphere. Thus there is not a standard CIRCUIT as we know it, with an anode and a cathode.
The double layer isolates, and at the same time feeds the inner plasma.
There is, no doubt, a much different voltage below the photosphere than there is at the heliosphere, but I would not characterize the sun as a "discharge." It seems more complicated.
There is evidence that the individual "flux tubes" of the solar wind are of similar size and correspond to individual granules of the photosphere.

(sorry, I am unable to place the photo's here)A sketch of the flux tube texture of the solar-wind plasma. Each flux tube contains a
different plasma and the flux tubes move independently. An end view (right) depicts
the cross sections of the network of tubes. The scale sizes of the flux tubes correspond
to the scale sizes of granules on the solar surface. (From Borovsky, 2008).
So, is there a possible transformer/induction type of connection, at the granular scale, between each granule and its corresponding area at the bottom of the corona, across the chromosphere, which could be a significant part of how the sun works ?
I will save sunspots and the solar cycle for another time.
Thanks for your consideration.
