Will the current in a lightbulbconneted to a 220-v source be greater or less than the current in the same?

Question

bulb when it is connected to a 110-v source?

Answer 1

Greater. a lightbulb has a fixed resistance R

V = RI
I = V/R

So doubling the voltage will double the current.

Answer 2

Probably less because chances are it will burn out the filament ;)

But yes, all things being equal, doubling the voltage with a fixed resistance will yield approximately double the current (and light, and heat...)

Hope this helps!
