Enter the total temperature change (C), the total time (hr), and the total resistance (ohms) into the Resistor Temperature Coefficient Calculator. The calculator will evaluate the Resistor Temperature Coefficient. 

Resistor Temperature Coefficient Formula

The following formula is used to calculate the Resistor Temperature Coefficient. 

RTC = dT / (t*R)


  • RTC is the Resistor Temperature Coefficient (C/(hr-ohm))
  • dT is the total temperature change (C) 
  • t is the total time (hr) 
  • R is the total resistance (ohms) 

How to Calculate Resistor Temperature Coefficient?

The following steps outline how to calculate the Resistor Temperature Coefficient.

  1. First, determine the total temperature change (C).
  2. Next, determine the total time (min). 
  3. Next, determine the total resistance (ohms). 
  4. Next, gather the formula from above = RTC = dT / (t*R).
  5. Finally, calculate the Resistor Temperature Coefficient.
  6. After inserting the variables and calculating the result, check your answer with the calculator above. 

Example Problem:

Use the following variables as an example problem to test your knowledge.

total temperature change (C) = 30

total time (hr) = 2

total resistance (ohms) = 50

RTC = dT / (t*R) =  ?
