The actual value is 120000. In this gold tolerence is +-5% thus 5* (120000/100) =60000 !

@Anitha
Do know how to percentage calculations ?
5% means 5/100(120000)= 6000. Okay.

According resistance value codification
Brown =1 red=2 yellow=4 Gold=5%
the value of resistance 120000ohm =120000/1000=120K
but here maximum value refers to 126,000
Brown =1 red=2 yellow=4 Gold=5%
the value of resistance 120000ohm =120000/1000=120K
but here maximum value refers to 126,000

120000*5/100=6000+120000=1260000

First two colors are digits: Brown-1 & red -2.
Third color yellow is multiplier: Yellow -10000.
Last color is tolerance: Gold- 5%.
(12*10000)+/_(5% of 120000) = 126000 (max).
Third color yellow is multiplier: Yellow -10000.
Last color is tolerance: Gold- 5%.
(12*10000)+/_(5% of 120000) = 126000 (max).

Because we are not know the value of RES without multimeter or ohm meter so colour is best option.

Please tell me about colour coding of resistances and how to calculate the values of RES ?

Answer is 126000.
Because,
Brown-1.
Red-2.
Yellow-4.
Gold-tolerance of 5%.
120000 + 5% = 126000.
Because,
Brown-1.
Red-2.
Yellow-4.
Gold-tolerance of 5%.
120000 + 5% = 126000.

Brown - 1.
Red - 2.
Yellow - 4.
Brown red yellow,
12*10^4=120000.
Tolerance 5%.
Tolerance 5*(120000/100)=6000.
So 120000+6000=126000.
Answer is 126000.
Red - 2.
Yellow - 4.
Brown red yellow,
12*10^4=120000.
Tolerance 5%.
Tolerance 5*(120000/100)=6000.
So 120000+6000=126000.
Answer is 126000.

I got answers 120000, by not adding +_ 5%. By adding 5% the answer is 126000.
