| Abstract: | The principle to set up nominal values of the resistors is discussed.Queries and suggestions are proposed to nominal values of the resistors promulgated by the Electronic Industry Ministry of China.According to permissible deviation,the general expression to calculate nominal values of the resistors is developed.The absolute values of the errors calculated by the author are compared with the ones issued by the Electronics Industry Ministry of China.Based on the comparison,it is found that the standard deviation obtained by the author is smaller than one promulgated by the Ministry.Finally,the method to select values of the resistors is given. |
