As a result of the evaporation of tungsten from the filament surface of an incandescent lamp, the filament becomes thinner.

As a result of the evaporation of tungsten from the filament surface of an incandescent lamp, the filament becomes thinner. How does this affect the power consumed by the lamp?

With a decrease in the cross-section of the wire of the heating element, the current power decreased, because the resistance of the heating element increased and the current strength decreased.
