Question

what is colour code for a 220 Ω 10% and 1.2 k Ω 5% resistor​

Answer 1

The colour code for the given carbon resistors are:-
1) Red Red Brown Silver
2) Brown Red Red Gold .
The percentage is for the error correction which is for :-
Gold = 5%
Silver = 10%
No colour = 20%

Answer 2

Answer:

The color code is Red Red Black Gold in 5%.

Explanation:

• A resistance can be differentiated with small as well as large in size.
• The resistance is generally, understood with color coding in the resistance.
• It is painted to differentiate to agree with usage of any kinds of resistance.
• We can find the resistance body is written with number or letters, and it is mainly about the tolerance, resistance value and rating level of the watts.

• The colors of the resistances are of different kinds. They are:

1) Color of band A and B:

It will indicate the tow significance of figures in resistance of ohms.

2) Color of Band C:

It will indicate the multiplier of the decimal and calculated by the number of zeros it has followed by significant figures of two.

3) Color of Band D:

It indicates the percentage of tolerance which indicates the value in accuracy of the percentage of an indicate value.

4) The Gold is + or – of 5% and silver is + or – 10%.

The above related to gold and silver will be satisfied due to factor when there is marking of the resistance of the carbon, having a tolerance of 20%.

Given that:

Resistance = 220 omega

Tolerance = 5%

Code for red in values (AB) is 2

Code for black in values (AB) is 0.

We know that, the tolerance of gold is 5%.

Therefore, the resistance = 220

                                        = $2 * 10^{2}$ +$2 * 10^{1}$ + $0$

Hence, the color code is RED RED BLACK GOLD in $5%$%.
