In summary, the relationship between resistor temperature variation and temperature refers to the change in resistance of a resistor as the temperature changes. The term "2K" is used to describe the change in resistance of a resistor by 2,000 ohms at 0°C or room temperature. The resistor temperature variation is not the same for all resistors and can vary depending on the type and materials used. It is typically measured using a temperature coefficient, which is provided by the manufacturer. This variation can affect the performance of a circuit, so it is important to consider when designing a circuit.

Every resistor has some variation with temperature.
Let's say I pick a 2K resistor. Is the 2kohm specified at 0 deg C or room temp?

You need to read the spec of the resistor. The good ones tell you all that. For the cheap ones, you can still find the general spec. This is so specific you cannot give a general answer. Go to site like Vishay or Caddock and they should have plenty of materials for you to read.
 

1. What is the relationship between resistor temperature variation and temperature?

The resistor temperature variation refers to the change in resistance of a resistor as the temperature changes. This means that the resistance of a resistor will increase or decrease as the temperature changes.

2. What does 2K mean in relation to resistor temperature variation?

2K refers to the change in resistance of a resistor by 2,000 ohms at 0°C or room temperature. This means that the resistance of the resistor will increase or decrease by 2,000 ohms when the temperature changes from 0°C to room temperature or vice versa.

3. Is the resistor temperature variation the same for all resistors?

No, the resistor temperature variation can vary depending on the type of resistor and its materials. Some resistors may have a larger or smaller change in resistance with temperature compared to others.

4. How is resistor temperature variation measured?

Resistor temperature variation is typically measured using a temperature coefficient, which is a unit that describes how much the resistance of a resistor changes with temperature. This coefficient is usually provided by the manufacturer of the resistor.

5. Can resistor temperature variation affect the performance of a circuit?

Yes, resistor temperature variation can affect the performance of a circuit as changes in resistance can alter the flow of current and voltage in the circuit. It is important to consider the temperature coefficient of resistors when designing a circuit to ensure proper functioning.
