ANSWER:

a. 240 ohms

STEP-BY-STEP EXPLANATION:

Given:

Voltage (V) = 120 V

Current (i) = 0.50 A

We can calculate the resistance using the following formula:

[tex]\begin{gathered} R=\frac{V}{i} \\ \\ \text{ We replacing} \\ \\ R=\frac{120}{0.5}=240\text{ ohms} \end{gathered}[/tex]

Therefore the correct answer is a. 240 ohms
