The current strength will be determined by Ohm’s law

I = U / R.

Resistance R is the sum of the internal resistance of the current source and the load resistance

R = Rb + Rn;

I = U / (Rv + Rn).

With a short circuit, the load resistance is zero, therefore

I = 36 / (4 + 0) = 36/4 = 9.

Answer: short-circuit current strength 9 A.
