Question

two bulbs are connected to voltage 220V and the power of the bulbs are 100W and 60W respectively .Find the resistance if both bulbs​

Answer 1

Explanation:

In a parallel circuit same potential is applied to all the branches.

Thus current drawn by 60 W bulb will be: 60/220 = 3/11 A (using Power = VI)

and by 100 W bulb is: 100/220 = 5/11 A

Thus total current drawn would be: (3+5)/11 = 8/11 A
