The total current supplied to the circuit as shown in the figure by the $$5$$ V battery is ______ A.

Based on the circuit analysis and Ohm's law, the total current supplied is calculated as follows:

The total current I supplied by the battery depends on the source voltage V and the equivalent resistance $$R_{eq}$$ of the circuit.

1. Given Parameters:

• Battery Voltage ($$V$$) = $$5\text{ V}$$
• Equivalent Resistance ($$R_{eq}$$) = $$2.5\ \Omega$$

2. Calculation using Ohm's Law:

According to Ohm's Law ($$V = IR$$):

$$I = \frac{V}{R_{eq}}$$

Substituting the given values:

$$I = \frac{5\text{ V}}{2.5\ \Omega}$$

Result:

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