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

Option: 1

zero


Option: 2

non-­zero but less than the resistance of the load


Option: 3

equal to the resistance of the load


Option: 4

very large as compared to the load resistance


Answers (1)

I=\frac{E}{R+r}

If r=0, then I=E/R that means current will be constant for a given load.

But if we talk about a general case, then if internal resistance is very large as compared to the load resistance, then we can neglect the load resistance in every case and the equation will become, I=E/r.

So for general case, we can say that internal resistance should be very large as compared to internal resistance for current to be constant
