What is the color code of tolerance band?

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

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.

But how come 120000 comes? Please reply asap.

Fulchand said:   1 decade ago
1 comes for brown;2 comes for red;10^4 comes for yellow so we get 12*10^4=120000.

What about Tolerance codes? Every tolerance is 5.

Sumitram said:   1 decade ago
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.

How many types of tolerance band of the resistor, and how they are abbreviate?
