Madilynn · Answer 1

If the new filament wire is made of the same substance as the old one

but is thinner, then its resistance is higher than the original one.

When constant voltage is applied to a greater resistance, the current

decreases.

B, I would presume since you don't have enough thickness in your wire as you did before.
