JEE MAIN - Physics (2005 - No. 9)
An energy source will supply a constant current into the load if its internal resistance is
very large as compared to the load resistance
equal to the resistance of the load
non-zero but less than the resistance of the load
zero
Förklaring
$$I = {E \over {R + r}},\,$$ Internal resistance $$\left( r \right)$$ is
zero, $$I = {E \over R} = $$ constant.
zero, $$I = {E \over R} = $$ constant.
