By using colour codes, we can calculate the resistance value without multimeter and colour code is the best choice to calculate resistance.

No its not 10% gold is 5%. why is it called as nominal value? Does it mean v shud not consider the tolerance??

red =2
red =2
0range =10^3
gold =10%
so value=22,000 ± 10%
red =2
0range =10^3
gold =10%
so value=22,000 ± 10%
