Abstract
Four major subjects in solar physics, the heating of the corona, the cause of the solar wind, the formation of sunspots and the cause of solar flares, are discussed on the basis of the electric current approach, a sequence of processes consisting of power supply(dynamo), transmission (currents/circuits) and dissipation(high coronal temperature, solar wind, sunspots and solar flares).This is because the four subjects have hardly been considered in terms of the electric current approach in the past, in spite of the fact that these subjects are various manifestations of electromagnetic processes. It is shown that this approach provides a new systematic way of considering each subject; (1) the long-standing issue of the coronal temperature, (2)the long-standing problem on the cause of the solar wind, (3)the presence of single spots(forgotten or dismissed in the past) and its relation to unipolar magnetic regions and (4) the crucial power/energy source and subsequent explosive processes of solar flares. The four subjects are obviously extremely complicated and difficult subjects, but it is hoped that the electric current approach might provide a new insight in considering the four subjects.

In solar physics, there are at least four major issues.1
There is one common weakness or lack in studying all the four subjects. It is the lack of considering them on the basis the electric current approach, which consists of a sequence of processes, power supply, transmission and dissipation.this sequence of processes is the basic way of studying electromagnetic phenomena
Summary
There are at least four major issues. 1. After the most extensive review based on multi-satellite observations and others, Fletcher et al (2011) are uncertain about the role of magnetic reconnection as the energy source process. The electric current approach considers solar phenomena systematically as a sequence of processes, which consists of power supply (dynamo), transmission (currents/circuits) and dissipation (solar phenomena) He repeated this point later (Alfven, 1977, 1981,1986). There is one common weakness or lack in studying all the four subjects It is the lack of considering them on the basis the electric current approach, which consists of a sequence of processes, power supply (dynamo), transmission (currents/circuits) and dissipation (observed phenomena).this sequence of processes is the basic way of studying electromagnetic phenomena. It seems that this approach seems to provide a new way of considering them
