Aren't parallels supposed to not have the same brightness? Please enlighten me.

Conceptual Example rightness of bulbs in
parallel
Which lightbulb in the circuit of FIGURE below is
brighter: A or B? Or are they equally bright?
А
В
Identical
bulbs
Conceptual Example Brightness of bulbs in
parallel (cont.)
1. The potential at these two
points is the same because
there is no potential
difference across the wire.
В
AVA =AVB
3. The potential differences
***. across the two bulbs must
be equal.
2. The potential at these two
points is the same as well.
