- 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.arrow_forwardAll six bulbs in the circuit illustrated in the figure are identical.
