# An energy source will supply a constant current into the loads of its internal resistance is

$\begin {array} {1 1} (A)\;equal\: to\: the\: resistance\: of\: the\: load \\ (B)\;very\: large\: as\: compared \: to \: the\: load \: resistance \\ (C)\;zero \\ (D)\;non-zero\: but\: less\: than\: the\: resistance\: of\: the\: load \end {array}$

$I = \large\frac{E}{R+r} \sim \large\frac{E}{r}$
Hence, the energy source will supply a constant current into the loads if its internal resistance is very large a compened to the load resistance.
Ans : (B)
