Answer

20 V

To calculate the potential difference (voltage) across a resistor, you use Ohm's Law.

Step 1: State Ohm's Law Ohm's Law states that the potential difference ( $V$ ) across a resistor is directly proportional to the current ( $I$ ) flowing through it, and the resistance ( $R$ ) of the resistor. $V = I \times R$ Where: • $V$ is the potential difference in volts (V). • $I$ is the current in amperes (A). • $R$ is the resistance in ohms ( $\Omega$ ).

Step 2: Apply the formula with an example Let's say a current of $2 \text{ A}$ flows through a resistor with a resistance of $10 \Omega$ . $V = 2 A \times 10 \Omega$ $V = 20 \text{ V}$
