Which statement is correct The 60 W bulb has a greater resistance and greater current than the 100 W bulb The 60 W bulb has a greater resistance and smaller current than the 100 W bulb The 60 W bulb has a smaller resistance and smaller current than the 100 W bulb The 60 W bulb has a smaller resistance and greater current than the 100 W bulb We need to know the resistivities of the filaments to answer this question يقوم الانتقال إلى سؤال أخر يحفظ هذا الرد - # . = = م

Answer 1

Correct statement is : The 60 W bulb has GREATER resistance and SMALLER current than 100 W bulb

Explanation is given below

100 = . PA = 60W, IB = 100w, v=llov PA = ² PA = V R = V² = (110) ² = 2020 PA 60 - RB = y² = (10)² = 1212 IA V = 100 = 0.545A Ig= V = 110 = 0.909 A i RA > RB and IATIB : The Gow bulb has greater resistance and smaller current than 100 w bulb 202 3 RB 121
