The plus-minus limits of a resistor's marked value are referred to as its tolerance. Tolerance indicates the acceptable range of variation from the specified resistance value, usually expressed as a percentage. For example, a resistor with a marked value of 100 ohms and a tolerance of ±5% can have an actual resistance between 95 ohms and 105 ohms. Tolerance helps in determining how closely a resistor's actual resistance matches its rated value.
You don't, you read the tolerance markings. If you measure the resistor and it is outside the marked tolerance it is bad.
in simple terms, band represent numbers, ex:- 10K resistor have different colour code and that is difference from 5k resistor. if you type in google 'resistor colour code' that will describe how to calculate a resistor value. thanks

If you mean the HVAC fan, the resistor should be located within the fuse block.
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.
If resistor X is steeper than resistor Y in a voltage versus current graph (I-V curve), it indicates that resistor X has a lower resistance value compared to resistor Y. The steeper slope means that for a given increase in voltage, resistor X allows a greater increase in current, following Ohm's Law (V = IR). Therefore, resistor X conducts more current than resistor Y for the same voltage applied.
