Because of 5% tolerance(last colour GOLD), this resistance may vary 5% of 120 000.

Minimum resistance value = 120 k - (120k * 0.05) = 114 k ohms.

Maximum resistance value = 120 k + (120k * 0.05) = 126 k ohms.

Minimum resistance value = 120 k - (120k * 0.05) = 114 k ohms.

Maximum resistance value = 120 k + (120k * 0.05) = 126 k ohms.

Brown 1, Red 2. Yellow 10^4, Gold +-5%.

The maximum value means + 5%.

12*10*10*10 * 10 = 120000,

120000*5/100 = 6000.

120000+6000 = 126000ohm.

The maximum value means + 5%.

12*10*10*10 * 10 = 120000,

120000*5/100 = 6000.

120000+6000 = 126000ohm.

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.

Minimum resistance value = 120000-6000 = 11400.

Maximum resistance value = 120000+6000 = 126000.

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.

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.

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.

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.

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.

5000.

Therefore; 120000+5000=125000.

This is the right answer.

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.

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?
