As the first two bands indicate the number, the third band indicates the multiplier, and the fourth band indicates the tolerance, the 10K Ohm resistor can be detected easily by figuring out the color bands.
10K Ohm Resistor Color Code Chart
Detecting the value of a resistor is crucial for an electrical circuit as each resistor value provides a specific resistance. Resistor color code comes with 3, 4, or 5 color bands which is the easiest way to detect the resistance of that resistor.
Resistor color code standards follow the IEC60062, which is used by worldwide applications. 10k Ohm use resistor color code for 4 bands. From the 4 bands chart, the first two bands indicate the number. While the third band indicates the multiplier, the fourth band indicates the tolerance.

Resistor Color Chart
From the chart above, you can see that each color denotes the value and each column indicates either digits, multiplier, or tolerance. For a 10k ohm resistor, we can see the first strip of color is brown, followed by black and orange. So, the brown indicates 1, black indicates 0, making it 10. While the multiplier value is 1K, making the whole resistor value 10k Ohm.
The fourth band is gold color, meaning the tolerance is +- 5%.
While the body color doesn’t have any meaning, the size of the resistor defines the power rating. The bigger its size, the larger its power rating.
How Do You Test a 10K Thermistor
To test a thermistor, you’re going to need a Heater, dry blower, or any type of heating device. For an NTC Thermistor, resistance decreases when the temperature is increased. A PTC thermistor reacts the opposite.
- First, check out its rated value before applying any heat to the thermistor. The thermistor’s resistance value should be very close to its rated resistance value. If you’re in a room where the temperature is higher than room temperature, it should be slightly less than the rated value. For a colder room, it should show a higher value.
- If the first observation went smooth, your thermistor is probably in a good shape. When you apply heat to the body of a thermistor, its resistance should begin to steadily decline within seconds after heat is applied if it is an NTC thermistor.
- While checking the multimeter resistance reading, a properly functioning negative temperature coefficient thermistor will show a smooth and steady decrease.
Are All 10K Thermistors the Same
Not all 10K thermistors are the same. It depends on the type of the thermistor. There are basically two types of thermistors, Negative Temperature Coefficient (NTC), and Positive Temperature Coefficient (PTC). NTC thermistors are commonly used in most circuits and instruments.
The defining characteristic of NTC thermistors is that their resistance decreases as temperature increases and creates the byproduct of residual heat. While PTC thermistors act in the opposite way of an NTC thermistor as temperature increases the resistance of the thermistor also increases. PTC thermistors are used to perform as a safety fuse function.
What Is a 10K NTC Thermistor

NTC stands for “Negative Temperature Coefficient”. A 10K thermistor resistance starts with an initial resistance value of 10K Ohm and decreases as temperature increases.
What Do 10K Ohms Mean
If a voltage source is at 6V, a 10K Ohm resistor allows you would have 6/10,000 amperes of current flowing in the circuit.
10k Ohm resistors are considered one of the most commonly used resistors so, you better buy them with a large number. You can remember the resistor color chart to easily detect any resistor value. For a 10K Thermistor, make sure to check the type of the thermistor as different types of thermistors have different functions and characteristics.
