Question

Hi, I am doing test corrections. I took another try at the problem and got (C). I'm not sure if it's correct or I even used the correct equations to help visualize the problem.

6. Two lightbulbs, lightbulbs 1 and 2, have resistance Ri and Ra, respectively, with R2 > R1. Which htbulb is brighter if they are connected in parallel to a 120 V potential source? Which lightbulb is brighter if they are connected in series to a 120 V potential source? Sane brightness z>R Lightbulb 2; lightbulb 2 Same brightness; same brightness Lightbulb 1; lightbulb 1 Lightbulb 2; lightbulb 1 Lightbulb 1; lightbulb 2 ow D. E. high hi

Explanation / Answer

V across the resistance in both the case = 120 V

P = V^2/R

So brighter bulb will be the one with lower resistance.

So answer will be R1

Option is C ( ans)
