Nominal value means nothing if our resistor value 3 digits means tolerance value 5 % , 4 digits means tolerance value 1%.
Red-2,red -2,orange 10^3,
=22*10^3,
=22000.
Nominal value is 1% ,bcoz resistor value is 4 digits.
The resistor value is 22000.
Red-2,red -2,orange 10^3,
=22*10^3,
=22000.
Nominal value is 1% ,bcoz resistor value is 4 digits.
The resistor value is 22000.

Yes nominal value is value without tolerance.

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

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