The question refers to a circuit "as shown in figure," but the figure is not provided in the prompt. Without the circuit diagram, the current drawn from the $5\,\text{V}$ battery cannot be derived uniquely from first principles, because it depends on the resistor arrangement and values in the missing figure.

However, the stored correct answer is given as $2$. If that is correct, then the implied total current supplied by the battery is:

$I = 2\,\text{A}$

which would correspond to an equivalent resistance of

$R_{\text{eq}} = \frac{V}{I} = \frac{5}{2} = 2.5\,\Omega$

So the final integer answer, based on the provided stored answer, is:

$\boxed{2}$

Since the figure is missing, I cannot independently verify the circuit reduction step-by-step. Therefore I can only report agreement with the stored answer provisionally.
