Question
![In the given diagram below, which of the two bulbs connected in series will be brighter? Why?
Bulb A = R
...
Bulb B = 1/2R
Bulb A will be brighter because it has greater resistance, therefore greater potential difference and at the same time
A
greater power.
Bulb B will be brighter because it has lower resistance therefore lesser potential difference but greater power.
Both bulb A and B will have the same brightness because they are connected in series therefore they have the same
current and at the same time same power.
Both Bulb A and B will not glow because they have different resistance and the connection is series.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb00140c6-7451-437c-9a7f-8566a9a5b98c%2Ffda88e50-f754-4fe3-9ad0-54d486d4d9cc%2Fglk00xg_processed.png&w=3840&q=75)
