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.
