Two similar headlight lamps are connected in parallel to each other. Together , they consume `48 W` from a `6 V` battery . What is the resistance of each filament ?

`6 Omega`

` 4 Omega`

`3.0 Omega`

`1.5 Omega`

Text Solution

Verified by Experts

The correct Answer is:

Power consumed by each lamp is `24 W`. Hence , using `R = ( V^(2)//P )`, we find `R = ( 36// 24) = 1.5 Omega`.
