摘　　要：本文通过系列实验及大量计算,得出白炽灯电阻与电压的关系式为:U=aR^2+bR+C.并验证了此关系式的正确性,给出了此式的适用范围,讨论了系数 a,b,c.The relationship between the voltage and the resistence of bulb filament was found out by a series of experiments and calculations.It can be expressed in the following form .. U=aR^2+bR+c.The range in which the formula works and the coefficients of a,b and c were discussed.
