1. The problem states that we have a circuit with a current $I = 2$ A and a resistance $R = 5 \ \Omega$, and we need to find the voltage $V$. 2. We use Ohm's Law, which states that voltage $V$ is the product of current $I$ and resistance $R$: $$ V = I \times R $$ 3. Substitute the given values: $$ V = 2 \ A \times 5 \ \Omega $$ 4. Multiply the numbers: $$ V = 10 \ V $$ 5. So, the voltage across the circuit is 10 V, which corresponds to option c) 10 V.
