Resistance to Temperature Calculator

Formula

The formula to calculate the Temperature Change (ΔT) is:

\[ \Delta T = \frac{R(T2)}{R(T1)} - 1 \div a \]

Where:

ΔT – The change in temperature in degrees Celsius (°C).
R(T2) – The resistance at temperature 2 in Ohms (Ω).
R(T1) – The resistance at temperature 1 in Ohms (Ω).
a – The temperature coefficient of resistance.

Definition

Temperature Change (ΔT): The difference in temperature between two points.
Resistance (R): The opposition to the flow of electric current.
Temperature Coefficient (a): A factor that describes how the resistance of a material changes with temperature.

Example

Let's say the resistance at T1 (R(T1)) is 1000 Ω, the resistance at T2 (R(T2)) is 1200 Ω, and the temperature coefficient (a) is 0.004. Using the formula:

\[ \Delta T = \frac{1200}{1000} - 1 \div 0.004 = 50 \text{ °C} \]

So, the temperature change is 50 °C.
