When the value of resistance is less than 100 ohms, or when fractional values of an ohm are required, the letter “R” is substituted for the significant digits to represent the decimal point.

21、t figures. The resistance value designations are shown in table III. Standard values for every decade follows the sequence demonstrated for 10 decade to 100 decade in table IV. Resistance values not listed in table IV for the appropriate resistance tolerance are considered as not conforming to the s
