The resistor is identified by a colour code. Most common is the 4 band resistor, band values are as follows - Black- 0, Brown - 1, Red - 2, Orange - 3, Yellow - 4, Green - 5 , Blue - 6, Violet - 7, Grey -8, White 9. The 4 th band is the multiplier.If the picture above is headed "Chicago7" then check the colour bands, they are Blue, 6 green 5 , orange 3, indicating a 65 K ohm resistor.

What do the colours on resistor mean?
The colored bands on a resistor represent the resistor value and tolerance. The first two bands indicate the significant digits of the resistance value, the third band represents the multiplier, and the fourth band (if present) indicates the tolerance of the resistor. By decoding these colors, you can determine the resistance value of the resistor.
Describe the purpose of the coloured bands on a resistor?
The colored bands on a resistor indicate its resistance value and tolerance. By interpreting the color code, you can determine the resistance value of the resistor and the range within which the actual resistance may vary. This helps in identifying, sorting, and using resistors in electronic circuits.
How do manufacturers of resistors indicate the value of the resistance?
They use a color code. Colored bands on the resistor that tell the value. Some precision resistors have their value written on them.
What are resistor values defined by?
Resistor value is defined by the Resistance the resistor offers in Kilo ohms/ohms value given by color codes on the resistor.
What is a resistor whose value can varied over a range of value called?
Variable resistor. The value of the variable resistor can be changed at any given moment.
2 resistors unequal value are in parallel. Would the power dissipated by the resistor with larger ohmic value be greater than the power dissipated by the resistor of lesser value?
No, because the power dissipated in a resistor is proportional to the square of the current through the resistor but only directly proportional to the resistance of the resistor (I^2 * R) and the current through the lower value resistor will be higher than the current through the higher value resistor, the lower value resistor will usually dissipate more power.
What is the relation between the size of the resistor and its value?
There is no relation between the resistor's ohms value and its size. The power of the resistor can be seen by its size. If the power is too small, the resistor can be destroyed.
What do the first 3 bands on a resistor indicate?
The first 3 band on a resistor indicate the value of that resistor.
Why resistor should disconnected from the circuit when measured the value of resistor?
if not disconnected you will measure the resistance of the circuit in parallel with the resistor.
Why resistor is used?
I want you to tell me the answer
How do you fix the value of a resistor?
It depends on what is wrong with the resistor. If it is damaged, replace it with the same type, value and power rating. If it is the wrong value and is not damaged, you can increase the value by placing another in series or reduce the value by placing another in parallel. If the resistor is variable type, you should be able to adjust it.
What is the largest value the resistor can be and still be in tolerance?
To determine the largest value a resistor can be while still being in tolerance, you need to know the resistor's nominal value and its tolerance percentage. For example, if a resistor has a nominal value of 100 ohms with a tolerance of 5%, the maximum allowable resistance would be 100 ohms + (5% of 100 ohms), which is 105 ohms. Thus, the largest value the resistor can be while remaining in tolerance is 105 ohms.
