Q. An energy source will supply a constant current into, the load, if its internal resistance is
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
Explanation
(c) $I = \frac{E}{R + r}$
$I = \frac{E}{R} = constant$
where, R=external resistance
r= internal resistance =0
