The resistance of filament in incandescent bulbs made from tungsten alloy and it is not linear. Cold filament has lower resistance and then heats up , resistance up and current decrease. | |

The time constant involved in filament heating and cooling is too long for it to care about the thyristor, just the RMS voltage applied to it and the current will match the voltage waveform in every point. | |
