Question

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

• A. very large as compared to the load resistance.
• B. equal to the load resistance.
• C. non zero but less than the load resistance.
• D. zero

Answer 1

The correct option is D zero

Here, $I=\frac{E}{r+R}$, If internal resistance is zero,

$I=\frac{E}{R}$=Constant
