... Coronal Heating: Basic 1-Fluid Plasma Equations I’m going to begin by writing down some basic one-fluid plasma equations that provide a framework for thinking about coronal heating processes. To derive these equations (which I’m not doing here), we could first write down the equations for electrons ...

... •If we use simple Coulomb’s law to solve the problem, charges on the conductors as well as the charge q1 should be taken into account. As the surface charges are unknown, this approach is difficult. • Instead, if we place an imaginary charge whose value is the negative of the original charge at the ...
