Question

Две электрические лампы ,мощность которых 40 и 100 Вт,рассчитаны на одно и то же напряжение .Сравните толщину и длину нитей накала обеих ламп Обоснуйте правильность своего ответа.

Answer 1

При равных рабочих напряжениях значение мощности пропорционально протекающему току, то есть через лампы мощностью 199 Вт, потечёт  ток большей силы и поэтому толщина её нити должна быть больше (чтобы не расправиться от высокой температуры накала)

Answer 2

Comparison of Filament Thickness and Length in Two Electric Lamps

When comparing the filament thickness and length of two electric lamps with power ratings of 40W and 100W, it is important to consider that both lamps are designed to operate at the same voltage.

The filament in an electric lamp is responsible for producing light when it is heated by an electric current. The thickness and length of the filament can affect the brightness and efficiency of the lamp.

Based on the available search results, there is no specific information provided regarding the filament thickness and length of the two lamps in question. Therefore, it is not possible to make a direct comparison or provide a definitive answer to this question.

However, it is worth noting that in general, higher wattage lamps tend to have thicker and longer filaments compared to lower wattage lamps. This is because higher wattage lamps require a larger surface area to dissipate heat and produce more light. Thicker and longer filaments can handle higher currents and generate more light.

It is important to consider that the design and construction of electric lamps can vary between manufacturers and models. Therefore, it is recommended to refer to the specific product specifications or consult the manufacturer for accurate information on the filament thickness and length of the lamps in question.

In conclusion, without specific information about the filament thickness and length of the 40W and 100W lamps, it is not possible to provide a definitive comparison. However, in general, higher wattage lamps tend to have thicker and longer filaments compared to lower wattage lamps.
