Question

An energy source will supply a constant current into the load if its internal resistance is

Accepted Answer

$$I = {E \over {R + r}},\,$$ Internal resistance $$\left( r \right)$$ is
zero, $$I = {E \over R} = $$ constant.

Answer

very large as compared to the load resistance

Answer

equal to the resistance of the load

Answer
