The current flowing to the third bulb will be diverted to the other two bulbs, so the other two bulbs will glow brighter.

Theoretically it is correct but practically it is wrong. Practically answer should be (B).

The remaining two lights glow same as earlier. Because in parallel circuit voltage is same. Since each bulb is receiving some currents separately, These will glow independently. Suppose third branch line is cutting, third bulb will not glow. The remaining two will glow continuously because these two bulb is receiving separate current from source.

Anand your answer is wrong. In series ckt current is same, if parallel voltage will be the same.

Anand said:   1 decade ago
In series circuit voltage remains same on each circuit, if parallel voltage is different.
