A resistor of resistance $5\Omega$ carries a current of $2\text{A}$. What is the potential difference across the resistor?

Step-by-step solution

1. Write Ohm's law: $V=IR$.
2. Substitute the given values $I=2\text{A}$ and $R=5\Omega$.
3. Calculate $V=2\times 5=10$.
4. Hence the potential difference is $10\text{V}$.

Concept tested: Ohm’s law (V = IR)
