Help on a physics homework problem?
I need help with a physics homework problem. An incandescent light bulb is supplied with a constant potential difference of 120 volts. As the filament of the bulb heats up, its resistance increases. What happens to the current flowing through the bulb in this scenario? Does it increase or decrease? I would appreciate any insights or explanations. Thank you!

The resistance increases with temperature increase so by Ohm's Law I = V/R the current will decrease
So the ans is 1
