	c is used for capacitance per unit (length/area/volume)
	I (or i) is used for current following the French who
	use I to denote :
	"L'Intensite' du courant" or "the current Intensity".
           -                                      -
	So in French EE textbooks, the problem would be to find,
	specifically, the current Intensity, as opposed to US textbooks, 
	where the statement of the problem would be something like:
	"find the current", which is not as accurate.
