Column-I and column-II contain four entries of column-I are to be matched with some entries of column-II. One or more than one entries of column-I may have the matching with the same entries of column-II and one entry of column-I may have one or more than one matching with entries of column-II. In fig. the resistance R is variable, r is the internal resistance of battery of e.m.f. E.

	Column-I		Column-II
A)	Terminal potential difference across the cell to be maximum.	P)	$R>r$
B)	Power transferred to R is less than the maximum possible.	Q)	$R<r$
C)	Power dissipated in the cell is maximum.	R)	$R=\infty$
D)	Fastest drift of ions in the electrolyte in the cell will be for.	S)	$R = 0$
		T)	$R = r$
