1.2.1.3 Resistance. The nominal resistance value expressed in ohms is identified by a four digit
number; the first three represent significant figures, and the last digit specifies the number of zeros to
follow. Where fractional values of an ohm, and values of less than 100 ohms are required, the letter "R"
is substituted for one of the significant digits to represent the decimal point. When the letter "R" is used,
the succeeding digits become significant. The following are examples of symbols for resistance values:
R050 = 0.05 ohm
1000 =
100 ohms
R100 = 0.10 ohm
1001 = 1,000 ohms
1R00 = 1.00 ohm
1002 = 10,000 ohms
10R0 = 10.0 ohms
Minimum and maximum nominal resistance values are as specified (see 3.1). The standard resistance
values for every decade will follow the sequence demonstrated for the "1 to 10" decade (see table II).
