This option is wrong. The correct answer is 120000 ohms.

Satish said: (May 10, 2011)  
Answer is right were we have to add max resistence ie 120000+5%=126000 ohms.

Saheb said: (Jun 7, 2011)  
Answer is partially right. It may be 120000-5%=114000 ohms

Santosh said: (Jun 12, 2011)  
My dear friends
answer is right question is asking about maximum resistance that should be possible with this colour code.
120000+6000= 126000

Murugaperumal said: (Aug 12, 2011)  
Brown =1 red=2 yellow=10^4 Gold=5%,
So=120000+5%, 120000+6000,
=126000.

Siva said: (Jan 9, 2012)  
Answer is right.

Shailaja said: (Jan 18, 2012)  
What is 6000? how it comes any explain please.

Anitha said: (Jan 27, 2012)  
The actual value is 120000. In this gold tolerence is +-5% thus 5* (120000/100) =60000 !

Kumar said: (Feb 12, 2012)  
@Anitha

Do know how to percentage calculations ?

5% means 5/100(120000)= 6000. Okay.

Ramesh said: (Apr 6, 2012)  
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

Giriraj said: (Apr 30, 2012)  
Formula for finding resistance is
for finding max value=(ABx10^C)+T%
for finding min value=(ABx10^C)-T%
where A= 1st band colour
B= 2nd band colour
C= 3rd band colour
T= 4th band colour (tolerance)

here in this question
Brown =1
red =2
yellow=4
Gold =5%

So acc... to formula
(ABx10^C)+T%
(12x10^4)+5%
we get 120000+((120000*5)/100)

So answer is 120000+6000 =126000 ohm

Sukh said: (May 15, 2012)  
120000*5/100=6000+120000=1260000

Rekha said: (Jul 11, 2012)  
Why are the resistance have a colour code ?

Parveen said: (Aug 16, 2012)  
Because we are not know the value of RES without multimeter or ohm meter so colour is best option.

Aditya Yadav said: (Mar 19, 2013)  
Please tell me about colour coding of resistances and how to calculate the values of RES ?

Pavani said: (Jun 28, 2013)  
Answer is 126000.

Because,

Brown-1.
Red-2.
Yellow-4.
Gold-tolerance of 5%.

120000 + 5% = 126000.

Manju said: (Aug 17, 2013)  
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.

Chandra Kumar Nayak said: (Sep 19, 2013)  
I got answers 120000, by not adding +_ 5%. By adding 5% the answer is 126000.

Dalmar said: (Nov 26, 2013)  
The right answer is 120000 Ohms + 6000 Ohms = 126000.

120000*.05 = 6000 the tolerance of gold.

Rathi said: (Nov 26, 2013)  
@Dalmar is Right.

Why we adding 6000?

Because they asking the maximum resistance value. So we should add the tolerance of gold for 120000(120000*.05 = 6000).

If they ask minimum value we need to subtract 6000 from 120000.

Vignesh said: (Jan 7, 2014)  
I need the resistance value and how to calculate the resistance please with correct and know the answer.

Hemant said: (Jan 16, 2014)  
Answer is right were we have to add max resistance i.e. 120000+5% = 126000 ohms.

Ilakkiya said: (Mar 21, 2014)  
I need a separate resistance value and how calculate the correct answer?

Jayaprasad said: (Dec 19, 2014)  
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).

Biswaranjan Das said: (Jan 4, 2015)  
Wrong answer.

Answer is according to resistor color code.

B B R O Y Great Britain Very Good Wife.

It shows black, brown, red, orange, yellow, green, blue, violet, grey, and white in 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 respectively.

That's why resistance is 120000.

And tolerance of gold is 5%.

So it become 120000+6000 = 126000.

Nani said: (Feb 1, 2015)  
What about Tolerance codes? Every tolerance is 5.

Tina said: (Jul 22, 2015)  
But how come 120000 comes? Please reply asap.

Fulchand said: (Jul 30, 2015)  
1 comes for brown;2 comes for red;10^4 comes for yellow so we get 12*10^4=120000.

Jose Praveen said: (Sep 14, 2015)  
Brown = 1.

Red = 2.

Yellow = 10^4.

12 x 10000 = 12000.

Ol = + or - 5 tolerance.

12000 x .05 = 6000.

12000+6000 = 126000.

Ans: A.

007 said: (Nov 2, 2015)  
Why gold tolerance is 5%?

Ningappa Nidoni said: (Feb 12, 2016)  
Right answer maximum 126000 and minimum 114000.

Pramendra Kumar Yadav said: (Mar 31, 2016)  
Right answer A.

=> brown = 1
=> red = 2
=> yellow = 10^4
=> resistance = 120000
=> tolerance 5%

Max resistance = 120000 + 12000 x 0.05 = 126000.

Roja said: (Apr 29, 2016)  
Still I have a doubt. I don't understand how to resistance where three color codes are present with tolerance.

Please clear my doubt.

Sujay said: (Apr 29, 2016)  
What is the color code of tolerance band?

Sujay said: (Apr 29, 2016)  
How many types of tolerance band of the resistor, and how they are abbreviate?

Sumitram said: (Jun 17, 2016)  
The right answer is 1260000 ohm.

It is because brown = 1, red = 2 and yellow = 4 log10.

Therefore, resistance = 120000 and tolerance is 5%.

So, max resistence = 120000 + 5% * 120000 = 126000.

Mustufa said: (Aug 22, 2017)  
The actual value is 120000 but due to 5% tolerance of the gold it becomes.

5000.

Therefore; 120000+5000=125000.

This is the right answer.

Venkat said: (Sep 14, 2017)  
EVERY ONE IS RIGHT UP TO 120000 NEXT IS DOUBT +5% or -5%. It is simple +5% for maximum resistance (120000+6000) and -5% for minimum resistance (120000-6000). In question maximum resistance asked so 120000+6000=126000.

Gift said: (Apr 30, 2018)  
The answer is 126000.

Pranay said: (Nov 14, 2018)  
Answer A is right.

Question asking for "The maximum resistance value for a brown, red, yellow, gold".

So,
Brown 1.
Red 2.
Yellow 4.
Gold ±5%.

Hence, 120000 x 5/100,
= 6000.

Now for maximum value,
So, 120000+6000,
= 126000.

Ebenezar said: (Dec 27, 2018)  
It is simple +5% for maximum resistance (120000+6000) and -5% for minimum resistance (120000-6000). In question, maximum resistance asked so 120000+6000 = 126000.

Pratik Khandla said: (Jan 27, 2019)  
Because of 5% tolerance(last color gold), this resistance may vary 5% of 120000.

Minimum resistance value = 120000-6000 = 11400.
Maximum resistance value = 120000+6000 = 126000.
