Answer 1

Answer:

I hope it's helpful for you

Explanation:

First of all joining a broken filament will be difficult. Secondly it cannot withstand the current like when it's not broken. The resistance will be lesser than before, therefore more current can flow through it, and bulb will emit more glow and temperature will also be more higher than before.
