How Do You Calculate The Temperature Of Coeffcient For Resistors?
For the design of electronic instruments, designers select resistors with specific resistance values. It is important that these resistor values are within a specific range, otherwise, the measurements made with these instruments will not be accurate. Because the value of a resistor changes with temperature, designers also must make sure the resistor value doesn’t change too much when the temperature changes. To ensure resistance change is minimized, designers measure and calculate the change in resistor value for a change in temperature value. The result of this calculation is called the temperature coefficient. Select a resistor. Find a resistor that you want to find out the temperature coefficient of. It can be any resistor and have any resistance value. Preferably, use a resistor with a value of one thousand or ten thousand ohms. For this example, we’ll assume a resistor of 1,000 ohms. Measure and record the resistor value at a temperature of 85 degrees centigrade. For this example
