electric current - Why does a 60W bulb glow brighter …

WebCorrect option is D) P= RV 2. We assume rated voltage of both bulbs is same so R∝ P1. thus, R 40>R 60. As they are connected in parallel so potential across them will be same i.e V. now, power dissipation , P∝ R1. thus, P 60>P 40 as R 40>R 60. Therefore 60 W bulb will give more lights. Was this answer helpful? Web$\begingroup$ @YlykCoitus - You're confusing yourself. The resistance of the inductor and of the lamp are in series, not parallel.Therefore they should be added up, like any two series resistances. I just thought it would be easier to think of it as a perfect inductor (zero resistance) in series with a resistance, since your inductor does have a resistance. solid wood bench seat
