To find the voltage applied to the circuit, you can use Ohm's Law, which states:

\[ V = I \times R \]

where:
- \( V \) is the voltage,
- \( I \) is the current (in amperes),
- \( R \) is the resistance (in ohms).

Given:
- Current, \( I = 3.6 \, \text{A} \)
- Resistance, \( R = 5.0 \, \Omega \)

Now, substituting the given values into the formula:

\[ V = 3.6 \, \text{A} \times 5.0 \, \Omega = 18 \, \text{V} \]

So, the voltage applied to the circuit is **18 V**.
