Question

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

Answer 1

Answer: (C)

zero

Answer 2

$I=\frac{E}{R+r}$ $I=\frac{E}{R}=$ constant where, $R =$ external resistance $r =$ internal resistance $=0$
