Question
In the circuit to the right, bulbs A and B are identical, and they are both glowing. What are the effects of these various actions?
I see this question has been posted two times before, but the answers all have comments saying they are wrong. If you can solve this I will be very happy and impressed :]
In the circuit to the right, bulbs A and B are identical, and they are both glowing. (6 points) a. Bulb A is removed from its socket.

2.a if we remove the bulb A.
Bulb B will go out. because since bulb A is in series with rest of the circuit. So after removal of A , circuit become open and bulb B will go out.
2.b if bulb B will be removed
Bulb A become dimmer because total resistance of the circuit became higher and current through bulb A become less so it will get dimmer.
2.c if a wire is connected between point 1 and 2
The bulb A become short so it will go off and bulb B will get brighter because voltage and current of B will increase so brightness will also increase of B
