The output of a tungsten filament lamp depends on the Temperature of filament.
The size of the lamp refers to the overall dimensions of the bulb, which can affect the amount of light that is emitted.
A larger bulb may have a larger filament and a greater surface area, which can lead to more light output.
The size of the shell, or the outer envelope of the bulb, can also affect the amount of light output.
A larger shell may allow for more heat dissipation and less absorption of the light, resulting in higher efficiency and greater output.
The temperature of the filament plays a crucial role in the amount of light output.
As the filament temperature increases, it emits more energy in the form of visible light. However, as the temperature increases, the filament becomes less efficient at converting electrical energy into light, leading to a shorter lifespan of the bulb.
