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

I=(E/R + r) I≈ (E/r)=constant where, R=external resistance r= internal resistance such that r>>R

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

Equal to the resistance of the load

Very large as compared to the load resistance

Zero

Non-zero but less than the resistance of the load

$I = \frac{E}{R + r}$
$I \approx \frac{E}{r} = co n s t an t$
where, R=external resistance
r= internal resistance such that $r >> R$

I=R+rE​ I≈rE​=constant where, R=external resistance r= internal resistance such that r>>R

$I = \frac{E}{R + r}$
$I \approx \frac{E}{r} = co n s t an t$
