Questions
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?
detailed solution
Correct option is D
Power consumed by each lamp is 24 W. Hence, using R = (V2/P), we find R = (36/24) = 1.5 Ω.Talk to our academic expert!
