The Incandescent Lamp block models an incandescent lamp, the key characteristic of which is that the resistance increases as the filament warms up.

Under the simplifying assumption that the rate of heat loss from the filament is proportional to temperature difference to ambient, the temperature of the filament is governed by

and the filament resistance is governed by the following equation

R=R0(1+αT)

where:

R0 is the initial resistance at turn-on (when filament is at ambient temperature).
T is the filament temperature relative to ambient temperature.
α is the resistance temperature coefficient.
tc is the thermal time constant.
k is the heat transfer coefficient.
R is the filament resistance.
i is the filament current.
