Mirza Baig said: (Mar 29, 2011) | |

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. |
