When does a lightbulb carry more current, (a) immediately after it is turned on and the glow of the metal filament is increasing
emmasim [6.3K]

A  lightbulb carries more current immediately after it is turned on and the glow of the metal filament is increasing; option A.

<h3>What is current?</h3>

Current refers to the flow of electric charges typically electrons.

Current flowing through a metallic material decreases with increase in temperature of the material.

This is because the resistance of the metal increases with increase in temperature.

Therefore, for a light bulb, the current flow through it will be maximum when it is just turned on because the temperature, and hence the resistance of the  filament is at its lowest.

In conclusion, current flow decreases with increase in resistance.
