32. An electronic device designed to operate at any
temperature in the range from –10.0ºC to 55.0ºC contains
pure carbon resistors. By what factor does their resistance
increase over this range?


Expert Answer

Step 1


range of temperature = -10o to 55o C.

thermal constant of carbon = 0.5×10-3 /oC.

Step 2

The resistance increment factor is given as,
