In this problem, we have been given a battery with that battery.
00:07
We have been given two bulbs.
00:09
Let's say i'm showing the bulbs with resistors.
00:15
All right, let's say this is my first bulb and this is my second bulb and this is my voltage source.
00:22
And they are connected in series.
00:24
So this is my circuit diagram.
00:27
First of all, we have to, in the first part of the question, we have to, in the first part of the question, to compare the brightness of both bulbs.
00:36
All right, the brightness of both the bulbs.
00:41
As both bulbs are identical, they are same.
00:45
And let's say the current flowing through them is i.
00:49
All right.
00:50
And as they are connected in series, so same current will be flowing through them.
00:56
If same current is flowing through them, then brightness depends on power...
