Question

. What is the resistance of a light bulb that uses 0.50 A while plugged into a 120V outlet?a. 240 ohmsb. 120 ohms.c. 60 ohmsd. 480 ohms

Answer 1

a. 240 ohms

Explanation:

Given:

Voltage (V) = 120 V

Current (i) = 0.50 A

We can calculate the resistance using the following formula:

`\begin{gathered} R=(V)/(i) \\ \\ \text{ We replacing} \\ \\ R=(120)/(0.5)=240\text{ ohms} \end{gathered}`

Therefore the correct answer is a. 240 ohms
