| 摘 要： | 有关白炽灯的计算，一般是把其电阻当作定值处理的。由于灯丝电阻受温度影响而呈非线性变化，因而计算的结果一般误差很大。在进行相关计算时，如果实际电压或电流与额定值相差较大，就应考虑灯丝电阻的非线性影响。利用灯丝电阻的伏安特性曲线，计算的结果比较准确。

| Abstract: | The electric resistance of incandescent lamps is previously calculated as a fixed value. However, because the filament resistance varies nonlinearly under the influence of temperature, the error of the calculating result is always great. In the relevant calculation, if there is great difference between the actual voltage or the current and the rated value, the non-linear influence of the filament resistance should be taken into consideration. The calculation will be convenient and its result will be accurate with the volt-ampere characteristics curve of the filament resistance. |
