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%

Why to use the colour code only for resistance? please anybody explain.
Meera said:

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