This R, therefore, is between 2565Ω and 2835Ω. The calculations are as
follows:

5 percent of 2700 is 0.05 x 2700 = 135

For +5 percent, the value is
2700 + 135 = 2835 Ω

For -5 percent, the value is
2700 - 135 = 2565 Ω

Example 2:
green blue orange silver

green blue orange

5 6 x 1000 = 56000Ω

Therefore, the R value is 56000Ω or 56kΩ with tolerance +10%. (Silver
is 10%-please refer back to table 1)

Example 3:
orange orange black gold

The example 3 illustrates that black for the third band just means “do not
add zeroes to the first two digits”. Since this resistor has orange, orange,
and black band, the R value is 33Ω with tolerance +5%.
Example 4:

brown grey black silver

18 x 1 = 18Ω
Therefore, the R value is 18Ω with tolerance +10%.
