Answer:
a
When the both bulb are in the circuit bulb B glows equally brighter to bulb A
This because the power delivered to the both bulb are equal
b
The bulb A on the right will glow brighter than the bulb A on the left due to the fact that the power supplied to bulb A on the right is higher than that gotten by bulb A on the left.
Explanation:
From the question we are been told that the two bulbs are identical
So their resistance denoted by R is the same
Considering the left circuit where the two bulbs are connected in series which mean that the same current is passing through them
The power that is been deposited on the circuit is evaluated as
For the fact that the power deposited on the bulbs are the same they will glow equally
When B is now removed and only A is left
For the fact that its only bulb A that is on that right circuit the power delivered to it would be greater compared to the left circuit bulb A
