Wire Wound resistor
1.1 額定電壓 Rated voltage 額定電壓係指對應(yīng)於額定電力的直流或交流（商用頻率之有效值）的電壓，由下式求得。 The rated voltage shall be the D.C. or A.C. (R.M.S. at power frequency) voltage which corresponds the rated power and the value of which is calculated from the formula below.
1.2 公稱電阻值 Nominal resistance values 公稱電阻值係按表-2之?dāng)?shù)乘以10n(n為整數(shù))之?dāng)?shù)值，其單位為歐姆(Ω)。 公稱電阻值之範(fàn)圍則按表-1所示。 The nominal resistance values shall be the numerical values given in Table-2 multiplied by 10 n (n is an integer) in the unit of ohm(Ω). The minimum resistance and maximum resistance shall be as given in Table-1.
